Since I’m so annoyed by Fairphone not fixing the issue I finally collected some crash logs.
I freshly reseted the quickstep app.To reproduce the crash I just need to swipe up to open the menu, swipe down to close it and crash.

And I’m not an Orange customer.
Edit:
Ok I’m totally missed that here is the actual soultion: FP4 Quickstep keeps stopping after A15 upgrade - - #139 by fkofler
this should be the one marked
