I solved it!
CoInitialize I'm calling in my code wasn't the cause.
Probably called in MFC code.
I used call CoInitializeEx with MTA at the start of the GPU process and it no longer crashes.
No message is output to debug.log either.
When I checked the operation with CEF 91 again, the GPU process crashed there as well.
But my application starts after the GPU process crashes 6 times.
There was a problem before CEF 91, which may have led to a crash in CEF 92.
My modified application works with both the debug version and the official build release version.
thank you!
