Constant CTD every flight now (ntdll.dll)

Hello everyone. I had a CTD yesterday on a flight from Split LDSP to LFKF Figari and on two more flights. for test purposes I flew this flight route again and then ctd with ntdll.dll.

Then the same route again with deactivated live weather. and I suddenly didn’t have a ctd anymore. OK. 2 more flights made without live weather and again no CTD.
OK. now to say the least, I think I was able to isolate the problem. the live weather probably has a problem.
Only for note live traffic I do not use anyway because I had many crashes in the past.
I hope I could help you. Of course, I continue to test.

Sry because of maybe bad English I used a translator.

Based in Scotland, currently into a flight just over 1hr. Have live weather and traffic off, and also multi-player off. Using REX to inject live weather.
Have noticed an FPS drop though, even at cruise.

What server are you using please I’m in UK too?

That has since been updated. Not sure why you would see an out of date one. It was updated on 10/06, 12 days before that one expired.

Check Windows and MS Store for updates. Then restart your PC even if the updates say no restart is required.

POSSIBLE FIX

Hello everyone,

Following our investigation, we are recommending you complete the below steps to resolve the ntdll.dll crash.

  1. Manually run Windows Update (Start → Check for updates) and install any available updates. (Note: there may be no updates available)
  2. Perform a full reboot of your PC (even if there were no updates detected in Step 1)
  3. Launch Microsoft Flight Simulator and test if you still get the ntdll.dll crash.

Some players who are reporting in this thread that the ntdll.dll crash now seems to be resolved may have already completed these steps.

Please note that this fix is specific to this particular CTD only and will not resolve any other crashes such as the “Memory could not be read” error. If you have been experiencing the ntdll.dll crash over the past few days, please try the above steps and report back in this forum topic if the crashing is now resolved or if you are still getting this CTD.

Thanks,
MSFS Team

No idea sorry.Just loaded it up and flew as per normal.All live data is on.i see some have switched to other servers.I havent.No FPS drop evident.

That sounds like it might repair a corrupt ntdll.dll file, but not necessarily address how it became corrupted in the first place.

Fingers crossed all the same. :slight_smile:

Ok no problem, happy landings :+1:t2:

In case it helps I already had the latest Windows 11 updates since friday (OS 22000.856) and latest MS Store (gaming services, Xbox app, etc). The error already reproduced with all that updated. I have not seen any further update available during the last days.

Cheers

I had an up to date Windows before and running an update check manually (right now) did not find anything to do. But I have the ntdll.dll crashes anyway. So I’ not sure if this is the main problem here.

(Sorry wasn’t meant for you Candy. Just a general response.)

Pmdg 737-800 won’t be causing problems because it’s not even released yet lol

Well they always said one good magnetic storm could kill the real internet instantly, so maybe that was just a prelude of things to come…12/21/12 baby!!!

@seedy - I do these steps everyday. Didnt help over the weekend. Though it seems back to normal here currently. On both win 10 and win 11 running beta 10 on this system

I done the windows update yesterday there was nothing new but there has since been an update for Windows defender… May just help never know

Have you performed a full system restart?

Does this include optional updates I tend to ignore them like forever with no issues … this cant be the root cause but appreciate you guys are investigating it further.

Optional updates shouldn’t matter, no.

We are fairly confident that this is, indeed, the root cause. We’re not 100% certain, though, so we appreciate everyone’s testing and reporting in this topic.

Still going to cause problems because I have zero updates to windows since last week before this started to happen so that’s not a fix. My windows updated before the weekend and has had no more updates since last week to windows however the crashes started in the Friday and been checking for windows updates daily with no updates available. And yes have done restarts either side.

Does windows update effectively do a “scannow”/repair windows command, whether there is anything to update or not?

I did W11 updates on 11/8 and 17/8.My first CTD with MSFS was on the 19th.Had 2 more then gave up until yesterday.
