My most recent CTD was this morning. I was sitting at a gate at KORD after landing the stock Cessna Citation. While chatting with ground services and changing external views with the hat switch looking for the fuel truck they assured me was on the road, it froze and crashed.

You are not just safe, but futureproof too, a decent 850W PSU can handle a 3080 pretty well. For me, it looks like the Logitech Microsoft Flight Simulator Plugin is the issue. With this, I had a CTD on the ramp. I’m going to file a ticket for both Logitech and Asobo, thanks guys.

Good luck, I would imagine they are already working on it but send them a ticket anyway as you can never know
Good evening all together. Someone has the same Issue ?
0xc0000409 with ucrtbase.dll.
Already changed Language, updated all drivers, Bios reset and a reinstallation of XBOX/MSFS.
The Ram is without faults and the harddrive is also New without faults tested.
My Rig :
AMD Ryzen 7 5800x
RTX 3080TI
32 GB Ram @ 3200 MHz
1000 Watt PSU
MSI B550 Gaming Plus Motherboard
I already checked if I have nahimic, logitech or any storage software installed. Nothing worked for me. Its loads a little bit but then crashes.

Two flights without problems gave me hope. Another gave me CTD during descent. Meh.
Full CTDs → reinstalled → Some CTDs → remove an unused keyboard profile → no CTDs for a week. Dam’ this sim is sensitive.

This seems often caused by rogue 3rd party liveries and aircraft when meeting other traffic or entering airspace … don’t use them unless their developers have provided an update and even then it’s not guaranteed.
hmm… yes… "Software Version: 8.0.213.0 "… may be you can check whether you have realy installed 64bit version, if not already done 
But I also searched a bit for a topic what I had in mind… not sure whether I found the one I searched, but here users also discuss about: Logitech Pro Flight Yoke System Issues
only installed English Language Pack US is necessary, not changing your windows langugae in generally.
Another reason was sometime that firewall or anti-virus solution blocks somewhat… Otherwise try to search a bit in forum with these two keywords, we have realy some topics about.

Well I tried a few things, but didn’t have too much time, so I wouldn’t make consequences yet. It looks like the yoke driver is fine, at least for me and for my 3 flights.
I could fly with my yoke, throttle and pedals totally fine. If I connect the switch panel and install the plugin for that, it crashes. The plugin starts with MSFS automatically and uses simconnect, and that’s the point, when CTDs happen.
I also tried one scenario: Yoke+throttle+pedals only, but flying with OnAir. It is a 3rd party “role play” add on, where you fly for your own company, it adds some economy to the sim. OnAir uses simconnect too, to extract a ton of data, like fuel, weight, position, speed, altitude, radio altitude, engine rpm, g-forces and so on. It looked fine, I started my flight from Italy to Greece, everything was okay until I turned from base to final. Normally at that point OnAir detects that you are landing at your destination, extracts the local weather and the announcer tells you the wind direction and speed. That was the point when I had a CTD. So it is very suspicious, that simconnect needs an update or MSFS needs to handle the data stream through simconnect better. (It was totally fine since november until SU5 happened)
Tomorrow I want to try one more thing: As 0xc0000005 is an acccess violation error, I will try to start both the Logitech plugin manually and MSFS as administrator. I don’t expect too much, but who knows.

Hi All,
My flight sim crashes on the startup screen with the loading bar at approx 80%. While displaying the FPS in developer it displayed a manipulator limit (red) followed by a main thread limit (red). The sim then crashes to desktop. I have tried numerous times and can’t seem to find a fix. The sim has worked for over a year now and this has never been an issue. Everything is up to date and I have made no significant changes that would result in the change of the sims functionality. Anyone have any ideas?
Im running it in boot camp, mac27inch 2021, Radon AMD 5500XT.
Thank you.
Well, my installation is clean at this moment, no liveries, generic models for AI and Multiplayer.
Hi nadson27,
Is your CTD like the one described in CTD at game launch after WU5 - PC Version Deluxe Steam
If so, please add your vote so that we get attention for the “specific” issue.
have agreat day 
I only know about an issue with external drives and bootcamp. So, may be you are affected from the 80% issue for which some topics exist… Often a xbox relogin helps, but there are also other possible reasons. Just search a bit in forum
When read through the posts according to CTD, I get the idea to get paied for bug analysing to find the cause. I have at different steps a CTD and it seems to be, that they occured randomly or not:
- After pressing start, to get into the cockpit CTD
- During the flight
- Retrun to main menu
- When I walk around on the world map
Does anyone have clue what will work? So what I tried so far:
- Checking drivers for updates
- MSFS updated
- Windows Update
- Lunching with and without empty community folder
It is a beautiful game, but my last flight with a duration of 1h is two or three month ago. Very sad. Even there a lot of nice sceneries, but in my opionion - why should I buy? I can`t use them.
So I`m very happy, when anyone has an idea…
Have a great day
Officially, no solutions offered have worked. Whatever progress we see is thanks to the R&D done by our fellow Simmers, who give suggestions which “might” help.
It’s over 60 days now and some (many?) can’t even launch FS2020 without a CTD! Not a word said by MS or ASOBO on what they are doing to address the CTD issues…
Losing hope very fast…
Check temperatures and enjoy your lunch

Hey guys!
The display driver nvlddmkm stopped responding and has SUCCESSFULLY recovered!
Thank goodness it was successful the umpteenth time it’s crashed the game!
I know MichaMMA, do this do that.
Just wish they would fix this with some clarity.
Hi MichaMMA,
Thank you. Sorry I forgot to mention I have MSFS installed on an external SSD. Could this be contributing to the issue? I still don’t understand how randomly it stops working. Thank you for your help. 
Cockpit screens going out and then CTD on Xbox series s and x
