Phone freezing and System UI not responding since Update 2 hours ago.

[Arlo]

Since the newest update for One UI 6 on my S22 ultra just 2 short hours ago. My phone has been freezing. I'm unable to do anything until it comes back. Then I get these

 

multiple pop ups saying "the system UI is not responding close app or wait"  this is occurring every few mintues or so.  I have cleaned out cache, I have even uninstall apps and ran device care.  Phone will be ok for a few minties and start the cycle of freezing and UI not responding again. 

Any Idea what could be going on?

Sounds like something might have gotten corrupted in the update download. Unfortunately this is above my pay grade and I hope someone has a fix for you.

You have to wait. I had same issue. It will resolve itself in due time.

@Arlo When you say that you have cleaned out cache, are you referring to the app's cache?

If you haven't done it yet, try wiping the device cache partition. This can clear out any corrupted or invalid cached values.

Something went wrong in the update process.
This can be resolved by flashing the OS to the phone using Odin.
There are numerous videos that will show you how to do this.
I advise a full backup first - a Google and or Samsung backup will handle most of your app data, but not WhatsApp or Signal, or Authenticator, and they now have specific backup and restore procedures
Be sure you've offloaded your photos, videos, and music files before hand as well before you do the flash.
I use Fridja to download the ROM for your device - again, YouTube will show you how this works. It will be a large download.
As far as I know, it only runs on windows, and be sure to have installed the Samsung USB drivers too.
You'll need a good data cable too.
You'll have the option to install over the existing OS or do a full wipe - which will take the device back to new phone setup level, but with the latest code. So this means setting up everything all over again. While this is a pain, I find that the device just work better when you do this.
All of this may sound daunting, but it's good to know how to do it, and no one step in hard at all. But it will be time consuming
