Does it do this in Safe Mode?

Ask for help to the FS Dream Team (GSX) guys. Looks something's wrong with their Couatl module and your installation, most probably it was not properly updated/installed, who knows?

just realised that link had my info on it lol

Thanks a lot for the help I did remove the whole program to test if it affects still and yes again crash of MSFS after an hour flight before landing :

I did upgrade my processor , memory recently to I9 however I did a copy of everything ( ghost copy) and recopied back but I did not reinstall everything back could this be the reason ? 

Should I delete MSFS2020 and reinstall the program again and all its supportive programs  ? I appreciate the advise

Are you overclocking anything? Memory, CPU, GPU? If you have had issues shortly after getting new hardware (a whole new computer), then it could well be that something is not correctly set up (or overclocked). MSFS is very sensitive to overclocking and things that work on other games can cause it to crash.

I would start by running MemTest and a 3d Mark stress test (or other stress tests) to make sure the system is fully stable first. Then look at MSFS specifically.

Exception code: 0xc000001d is an "invalid instruction" error.

All of us are running the same version of MSFS, so there obviously isn't an actual invalid instruction or we would all be seeing it. Therefore, you most likely have an issue with a supporting routine, like the VC runtime libraries or an OS module that is out of date.

If it was me, I would start by making sure that Windows was fully updated, and that all my Visual C libraries are fully up to date.

I just noticed the CPU upgrade part. Try updating the chipset drivers using the motherboard manufacturer's update checker.

I wanted to suggest you doing that, so you could have definitive proof GSX didn't had anything to do with the crash, but I see you already done that.

What really happened, and your test without GSX confirms it, the sim crashed for other reasons, and it **made** the Couatl engine crash because, when there's an abrupt crash like that, the Couatl engine, which it's a native, unmanaged, Win64 application so it's tasked to do its own memory clean up instead of relying on the .NET framework to do that, won't get a chance to do its normal cleanup on exit, because the "CLOSE" message from Simconnect it was waiting for never arrived and the connection with the sim was broken abruptly ( because MSFS crashed ), which caused the program to crash, with an Event in the Event Viewer.

This can easily mislead thinking Couatl64_MSFS.exe was the cause, when in fact it was the victim of the unrelated crash in the sim.

Thanks for all of you on all these suggestions I will start doing these suggestions and hopefully the issues will be resolved , I really appreciate all the assistance.
