group containers folder on desktop

Not sure why it's on the Desktop, it normally resides in..

/Users/YourUserName/Library/Group Containers

Start with this if M1, M2, or M3 Mac...

On your Mac, choose Apple menu  > Shut Down.

Wait for your Mac to shut down completely. A Mac is completely shut down when the screen is black and any lights (including in the Touch Bar) are off.

Press and hold the power button on your Mac until “Loading startup options” appears.

Select a volume.

Press and hold the Shift key, then click Continue in Safe Mode.

The computer restarts automatically. When the login window appears, you should see “Safe Boot” in the menu bar.

Does the problem occur in Safe Mode? 

Restart normally.

Start with this if IntelMac...

Safe Boot, (holding Shift key down at startup), does the problem occur in Safe Mode? Could take 10 minutes or more.

Safe mode attempts to repair Disks & clears lots of caches & loads safe Drivers, & prevents loading of 3rd party extensions, so if Safe Mode works try again in regular boot.

Is it an actual folder, or is it just an alias? If it has a little black arrow in the lower left of the icon, it's just an alias and you can delete it. Here's an example of an alias:

Good question!:)
