If you reboot and the issue goes away, it's not a hardware issue, so wouldn't be a "it's Samsung's fault so buy me a new phone" situation.
If it's that much of a bother, the best thing to do is Withdraw from the beta and Downgrade back to Android 11 /One UI 3.x
I understand your perspective.
Did you read the "Terms". I assume "no".
Samsung shall not be responsible for any such loss of data, any damages or any loss arising out of your use of the Beta.
... and later ...
