Hi, 

I have had this issue quite consistenlty now. The game dies after 10-15 minutes. 
The only thing I could see in the log is this

This *might* be it. I'll try and report back.

OK so I had a bit of a go yesterday and it seems to be working. 
I'll do some more testing before calling it a solution, but it appears deleting the OpenKneeboard.json reference (not the file, the reference) from the 

Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Khronos\OpenXR\1\ApiLayers\Implicit

registry location seems to have fixed the issue. More testing and then solution will be marked as solution.

I have OpenKneeboard installed since a couple of years, so it might be an old, improperly uninstalled version of OK... 

Just wanted @actually_fred to be aware of this too.

Yeah, that's been fixed since January

That said, it is a new thing (last month or two) that the old installations actually affect DCS.

Hi @SPAS79 . Is it fixed for good?

It has been working for the last few days so, yes. I guess that was the solution and I just marked it so. Thanks for the heads up, man!
