I just checked for updates for the heck of it and found a new update. It wasn't clear initially what it was, but it showed Sept 1 security patch, so I was a bit confused. It appears it's a stability update based on the change log.

Code:
Build Number : G991USQU4AUIL
Android version : R(Android 11)
Release Date : 2021-10-11
Security patch level : 2021-09-01
• Overall stability of your device has been improved.
• The security of your device has been improved

Nothing October about this AUIL update except its release.

The latest build rolling out to locked and unlocked U.S. devices is AUIN which does have the October Android Security patch.

Be wary... I installed the security patch Friday morning and for some strange reason it bricked my S21+ beyond repair and I was forced to purchase another one.

I couldn't do it myself nor could any tech at T Mobile resolve the issue. The phone.. An S21+ wouldn't stay turned on for more than 10 seconds.. It just kept cycling on and off.. So they couldn't get in..

That is interesting the next step is to send it to samsung. Did you trying doing a factory reset from the recovery menu?
