Personally I'd put the phone in Safe Mode which disables all downloaded apps but leaves the stock apps working and then see what happens just to make sure it's not a rogue app. If it stops then it's a process of elimination by deleting the most recent apps one at a time until the issue stops.
If this continues in Safe Modethen come out of that and then I'd try a factory reset and then set the phone back up without using any type of backup like Samsung Cloud if relevant, and and if that didn't help I'd have it swapped out in any applicable cooling off period @bluace

The advice I offer is my own and does not represent Samsung’s position.
