Learning Unity. Android app crashes

Hello. I’m new to unity and going through some simple learning tutorials with good success. I’ve been doing a simple game for android, and for a weeks I can not get it to work on my mobile. I install the app on android phone but the black screen opens and then turns off
I am sure I set up the project all correctly and using a google approved Samsung g13. Think it might have something to do with this changed 32bit to 64bit processing ? Can someone please help

Hello.
I did a new build and run and took screenshot logcat and console

I am not experienced in using Android, but breaking down this issue:
1 the build did work according to unity engine (console log)
2 can you play this build using the unity engine simulator function, does it work?
3 The first error is MBrainUtility (I see MBrainU) SecurityException < usually meaning it doesnt have the right access (Admin) etc. after that it struggles to find PackageManager < this too may be connected to the MBrain issue.
Possible resolutions (not used to android) - 1 have you got your android in developer mode, this basically overrides security settings…however does put the phone at risk (info is provided by android when you go to change the settings)
Is everything installed properly, double check, if in doubt, uninstall things and re-install

The processing shouldnt change all too much really, the more recent processing in computing is actually the 32bit, 64bit is older systems
