Random error keeps popping up during normal use of tablet

Hi, after updating to the public release of One UI 8 for the TAB S8 Ultra, I tend to keep getting this random error when in desktop mode

The default one ui home also tends to be unresponsive when in desktop mode

@SpikesGalaxy74 Did you wipe the device cache partition after the update? I recommend that you do this after every device update. It wipes out incompatible or outdated cache information which might be incompatible after the update. It does not erase any user data nor applications.

To wipe the device cache partition:

1. Power off your device and connect it via USB to your phone or a computer.
2. Power up while holding down the Volume up key and the Side key until the Samsung logo appears. 
3. An Android recovery menu will appear.
4. Use the Volume down key to scroll down to Wipe cache partition.
5. Click the side key to select it.
6. Use the Volume down key to scroll down to Yes. 
7. Click the side key to select it. The Cache will be wiped almost instantaneously. 
8. Click the side key to select "Reboot system now"

This wont erase my data will it?

No it will not erase data nor apps.

after doing this the error still shows up and basic use is limited

Probably the next step is to back up your data and do a factory data reset.
