A34 5G not responding after oneUI 7

[Tractor777]

My Samsung A34 5G recently got an update to one UI 7.0. finishing this update the phone occasionally (day one a day) will fail to respond to being woken up by pressing the power button. The screen just stays blank. After pressing the button a few times for a minute it eventually wakes up. There is an error message saying system process isn't responding. 

I have tried wiping the cache partition, deleting Google play service data and restarts.

Any ideas on other things to try out how to find out which system process is causing the problem?

Still early, but after the latest update, that's a whole day without a freeze.

After UI 7 update, two days ago I received a new update and now the phone is more stable even if all the issues have not been solved yet. 
One time the phone restarted by itself and today it freezes again.

Since the last update I didn't experience any new black screen issues, also tested to plug my phone to laptop, and select "charge only" instead of file sharing to see if the device will keep charging, as said in my previous comment, it was stopping the charge even though it looks like it's charging. So far both seems to be resolved, now, interestingly when I select charge only option it asks for my fingerprint, that wasn't happening before, but looks like it's fixed for now.
