The same to me. It happened at GND in EDDH cold&dark, maybe after I activated Simbrief-ID respectively Navigraph. Several times the same. After deleting WASM I was able to enter the cockpit again, but to finish MSFS2024 in the normal way it's not possible anymore, only by task manager.
I tried to activate Simbrief/Navigraph again, but freeze after that. No SU1 Beta installed - I know...
It's a pitty!
