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

Today for the first time, the sim is not crashing, not once.
My system is all the same from yesterday, when I couldn’t fly at all.

Could it be those FS 2020 Marketplace addons they’ve disabled now?
It it is, please take some holidays and don’t touch anything, anything!

I’ll be updating Zendesk tomorrow after more proper testing.

Cheers!
