There’s a possible fix here, I’ve just applied and about to test it out.
Let’s post our results here. Remember to create a Restore Point before modifying anything.
Cheers!
I use Resource Monitor (type it in the task bar search box) to monitor my memory usage.
While using the Crystal light, I can watch the commit values and the working set values for MS2024 continuously rise and my free memory continuously fall (goes to a low of about 300 MB) followed by a crash with the DXGI…CALL error.
I did notice that if I go into 2d when the memory usage is increasing, then go back into VR, the values will stabilize and I can then complete the mission without it crashing.
i did and no its not working for me
I have a gtx 480 super with 64gb ramm and 14 gen processor. I too had this error code, i used my stress testor and noticed my GPU and CPU hitting into the red . I found that lowering my settings 'sadly to a level not as graphically pleasing and using dlss auto with frame gen on and lowering LOD, the game ran without crashing after. Also i use DLSS swapper and make sure im using 3.8.10
Good luck hope this helps. 
Do you have the same issue if you follow the OP’s steps to reproduce it?
• I have the same crash also in VR using a Pimax Crystal Light and RTX4090 card. I can not get 15-20 minutes into a flight and then the crash happens no matter what I try.

EDIT - I disabled the OpenXR toolkit and thought that was the issue however I tried again today without it and still got this crash. I am continuing to troubleshoot.
Just started having this issue today. Twice the sim crashed me all the way to system reset (why can it do that?) Third time, I got this error message. I haven’t been able to fly at all.
This issue also starts to happen to me today. If I disconnect my 3 monitors and connect them again, it works, don´t ask me why. But If I exit the simulator and try to enter again the error message (0x887a0020) apears again…
After a lot of reading…
I found a solution in another post: delete the nvidia new app (my issues started after I installed it), go to Nvdia website and download the 566.03 version of the driver. Install it using the exe you downloaded and not using the Nvidea GEForce Experience.
After that everithing is working perfectly again for me.
Same issue. Started today
Same issue since latest MSFS update! Had no such issue before.
Yesterday everything worked flawlessly, today the error message is back…
I installed msfs2024 (I was waiting until it became more stable) just to check if the driver will work and it did.
I then tried to flight msfs 2020 again and got the same error …
Yes it is the same for me. Yesterday i could fly without CTD the whole day.
Today after 2 hours of flying CTD again.
I’ve tried everything with this……remove OpenXR tool, roll back the latest NVIDIA drivers to October version. Still get this CTD with about 20-30mins of starting a free flight with the Cessna 208. Also was happening with the Cessna 172 G1000. Funny thing was yesterday I was able to fly the 172 in career mode without this problem but today I still can’t begin a free flight without this crash. This was not a problem for me prior to the last MSFS 2024 patch so something in there has to be the cause. My computer is not overheating. I fly only in VR and now I can’t even use this sim. I hope this is fixed in the big upcoming patch!
I just flew 2 career flights with the Cessna 172 G1000 and then followed up with a free flight all in the same session and in the Cessna 172 and did not have this crash. This is just crazy and I cannot find a cause but my computer is not getting too hot and there was plenty of clouds and graphical goodness around to have caused an issue. I am going to try a free flight this evening in a different location and see if I have this issue there.
Tried a free flight again this evening in a different location with the Cessna 172 G1000 and got the INVALID_CALL CTD about 30 minutes in. I guess the career missions were not long enough to cause the crash even though I had a longer session in the sim I was going in and out of menus between missions so that might have been why. Seems like 30 minutes has been around my limit and this is happening now every full flight that I try to do no matter the aircraft. I’ve tried the C208 and Longitude in addition to the C172. I’m pretty certain this happened after last weeks patch as I’ve only been dealing with this since then. Prior I have completed 2 full flights since the sim was released. This has to be fixed as it is unusable for me in VR! I have not tried outside of VR because I am not set up to fly that way. I’m a bit concerned as I do not see any feedback or bug logged on this post and the next patch is coming next week.
