Microsoft Flight Sim 2020 crashing on start up

I wanted to post an update that I was finally able to fix my issue!

By scanning through my Windows Event Viewer I was able to locate where MSFS made a call out to the Open Composite OpenXR dll and got an error result, halting the game and dropping it to the desktop. This OpenXR file is a replacement dll for SteamVR. Even though I do not use VR on this new system (at least not yet), I do use it on my other gaming system and it looks like when I set up Steam on this new PC it copied my old preferences to use this dll over the native SteamVR dll's. OpenComposite and OpenXR is used in a lot of VR systems as it offers (usually) much better performance in SteamVR titles like DCS and MSFS 2020.

I installed and loaded the OpenComposite and Open XR toolkits and made sure that OpenXR was disabled and removed from this system and after I did that MSFS 2020 launched properly.

This obviously won't be a solution to all the issues reported in this thread but it should be a reminder to open up and look through the Event Viewer. For me, I was able to find the offending entry under Windows Logs>Application. Look for any red exclamation points with the "Error" label and see what it says.

Good luck and now back to some flying on my new rig!

It seems I already have the English (United States) Language Pack installed but it's not working. I tried to remove it but the remove button is grayed out. I then tried installing another language so I could try to remove and reinstall the English pack but every language pack I try just causes settings to close/crash. This is getting really frustrating, my son just really wants to play flight sim.

Hello Amr,

I have same issue. Game loads to 28 percent and then crashes. Error code is (0xc0000005) Since I have every module loaded in game not fleasable to uninstal and reinstall game again. This is my 6th reinstall. Before I write to you I have tried restarting my computer multiple times today. Google says I should check if my drivers are upto date. Which it is 24.4.3 AMD Addreline my computer specs are as follows:

Asus Rog Strix AMD RX570 drivers 24.4.3

Intel I9 11900

Game was bought online from Microsoft Store

Originally installed on Windows 10 64 bit upgraded to Windows 11 64 bit

Same here! 6th January 2024

Same situation, tried all of the above, all drivers are up-to-date.

The game launches, i click on an option (Training, etc), screen freezes for about 20 seconds or so, and full reboot occurs.

Tried in-game safe mode, no difference.
