MSFS2024 Crashes to desktop after xx minutes, between 10 and 20 minutes. Application Error

I did that yesterday, I could fly without crashing a couple of times, the third one, crash.
And today, same story.
The suggestion from Zendesk didn’t help either, it was a generic run the smc command, etc. Which I do regulartly.
FS2020 is working rock solid, better than ever before.
I don’t get it.
