Brief description of the issue:

Since April 4, 2023, with everything operating properly prior, all attempts to start MSFS 2020 result in a CTD before the main menu opens or after selecting a world location for a flight. This happens in normal or safe mode. Receive a crash report that says OnCrash: Msg=FiberError

Here is the crash report (expand this)

Welcome to the Forums.
This post will probably be moved as it is discussed elsewhere. Please use search.
Have you looked through Customer Support also?
The link for it is at the top of the Forum pages.

Doesn’t help you specifically, but this thread/post mentions FiberError

3

Hello,
Welcome to the forums!
I’m sorry to hear that you are having issues. We generally ask that people seek support in Community Support before logging bug reports. So I have moved your post to Tech Support where the community can provide answers. Best of luck!

4

Thank you. Have tried numerous approaches but no luck in resolving the consistent crash and mysterious repeated report of “FiberError.”

5

One thing you could try is to “Submit a Request” to Zendesk, from the “Support” tab at the top of the page.

6

as @ccrbc mentioned, we discussed same error messages while ago for a user with same problem and at the end he did a full re-install.

But may be you can try first the cleanup of appdata, rolling-cache, etc. before you start the “deletion of all” ( the folders are bit different than these one for a Steam-Install, but the location is often mentioned in forum ).

As I understand it, Safe Mode just disables the Community folder after a crash. It can be useful for initial troubleshooting if you suspect that something there is causing the crash, but that’s about it.

8

Safe mode disables all addons, Marketplace or Community Folder.

I’ve been having the exact same problem since early april.
Unable to load the game. CTD. Tried everything, including complete reinstall (incl all the online content). Nothing helps.

It all started, I think, with the latest MSFS update. I was running it before without any issue whatsoever. After this update intermittent crashes, gradually worsening to not being able to play anymore.

Created a zendesk ticket.

I have a similar problem. It first occured around a week ago, with the game crashing during startup. I did a complete reinstall, which fixed the problem, until now. I filed a Zendesk report, but here’s the CrashReport in case anyone is interested:

I also started seeing this issue earlier this week & haven’t been able to reliably run since then. Thought it had something to do with my messing around with FSUIPC7 but the issue persists even after uninstalling it & emptying Community folder. My crash report looks similar to @lukecologne2000 & same experience as @MochaWool584213: intermittent crashes, gradually worsening until now seemingly unplayable. Will try a fresh install.

After my message on 4/21 I bought a new high speed M.2 to insert into an empty M.2 slot. I did a fresh install of Win11 on it, and a fresh install of MSFS.

With that, I’ve been able to play stable for ~ 4 weeks. I played only the vanilla game (deluxe). Out of fear I’ve not even dared to open a browser on the system!

Then, out of the blue, exact same issue(s) resurface again.
While I was able to run stably, I did a complete image of this “working” m.2 disk, figuring if it starts to suck again I’ll just restore the “good” image.

No such luck!!

Even the restored image is now un-playable.

I think it started acting up in tandem with certain Win11 or game updates.

I tried zendesk issue as well. They just bury you in submitting all kinds of diagnostics but there is no follow-up or resolution.

Nothing to be done now but wait for whatever for the game to become playable again, hope they can fix this… this game is just too awesome.

Pretty much same experience… did a fresh install + updated my Nvidia drivers, and worked great for a couple of weeks. CTDs started happening after my flights this week and now crashing when starting up, again with FiberError in the crash logs.

Hello, same experience here
Since the Oceania Antarctica update, the game crashes everytime I try to launch it.
I did two clean re-installs, but still no success. All the drivers, Windows etc are up to date.
I get the error message “Fiber error” in the log, and created a Zendesk ticked, we’ll see what they may answer.

Hi @Labrigue , @mirthturtle , did you either of you guys (or girls!) have any luck with this CTD issue?

I just tried to give it another spin, after the new MSFS update, and a new Nvidia driver (which explicitly mentions fixing some DX12 MSFS crash fixes).

Unfortunately still no luck, I yearn to when I was able to fly in this beautiful scenic world! Sure hope whatever it is they gonna fix it soon… I might be temped to upgrade my jig hardware to the latest and greatest, if only some kind of confirmation would come.

Cheers,
H

Hey there; that’s disappointing to hear. Mine has been working normally since the reinstall + driver update, but I haven’t been using as much. In the meantime, yet another Nvidia update dropped today so fingers crossed things are getting fixed.

Hi Mochawool

After sending the crash report logfile to Microsoft support, they answered me with two troubleshooting tutorials, but before I even performed them, MSFS launched properly, without any specific other action from my side, so I don’t really know what happened and what made it launch again.

I can’t share links in this message here, so maybe ask the support direclty for these troubleshooting tutorials.

Best advice I can give as well is to find and delete any trace of your addons. Deleting the community folder alone doesn’t help since Windows creates “hidden” copies and logfiles everywhere. For example, delete as well this folder
…\AppData\Local\Packages\Microsoft.FlightSimulator_8wekyb3d8bbwe\LocalState\packages

Thanks for the follow-ups & hint about that new Nvidia driver!

I’m now able to play the game again, this is what I did compared to yesterday when I wasn’t able to run (CTD during loading):

  1. Grabbed the latest Nvidia, 536.40
  2. From the approaming folder, removed the fs-base-* packages
  3. Fixed the system time

Note about 3: I’m using Ubuntu exclusively, I just installed Win11 on a 2nd M2.SSD specifically to run MSFS, and only MSFS. Due to the mixup how these OSes handle system time, my windows system time was always off by 2 hours. I didn’t notice this and has prevented before from accessing stuff I bought on the marketplace.

See this resource about removing fs-base* packages.

Now’ I’m flying again from the world map without any issues whatsoever. Let’s see how long this lasts!

Hi MochaWool
This week my game started crashing again.
I have the same set up as you with the dual boot Ubuntu/Windows and the same time difference for Windows. Fixing Windows’ clock has immediately solved the problem (at least, hope so…)
I guess you hit a key thing that I had never read elsewhere, the correct tuning and synchronisation of the clock seems to be relevant for MSFS to behave properly
