I have a server where QB has been crashing since Memorial Day weekend.  My temporary resolution is running R3, which I still had from when I upgraded from QBE 2019 to QBE 2022.  On this particular server, QB wouldn't even open. I would get the splash screen, then nothing.  No details in Event Viewer, nothing in the logs.  Just a vanishing splash screen. So I've pretty much ignored all of the suggestions and workarounds because none of them apply to my situation.  I can't turn off the home screen or or hold the Alt key, because the application simply doesn't open.  Oddly enough, I have several three remote desktop servers that my users access and QB has been working fine.  I hold my breath every day that nothing changes that.
