Doubt it has anything to go with the OS as that’s the current one & I’m using it with no issues as are probably most people on here.
You could try re installing that version but doubt it’ll have an affect. That screen looks like it’s hanging during boot sequence.
Factory reset will hopefully sort it, I’m guessing by your apprehension you’re not backed up?
Screen isn’t showing any unusual characters which has been my experience when things have gone badly wrong in the past so fingers crossed a reset fixes it & you don’t have to send it back to HQ.
Good luck
