Fairphone 5 - System UI Crashes, and freezing on Android Bubbles

Hello, I have Fairphone 5 for 2 months, having the same problems, only it freezes in many more occasions: sometimes when someone calls, sometimes when opening e-mail (I use several e-mail boxes), I restart the system in average 3-5 times per day, is there any chance it will be fixed via updates? Before I had Fairphone 3, I remember also first months it was ustable, later ok, I use the same set of applications on F5 as before at F3 - there it was only slower, but stable.
