Linux Mint Upgrade from 22 to 22.1 leaves desktop unusable.

I have attempted the upgrade from Mint 22 to Mint 22.1 twice now. Both times failed. OS: Linux Mint 22 x86_64 Kernel: Linux 6.8.0-51-generic This is what I get <br>https://postimg.cc/1nSbY1NK<br> The menu is sometimes there and sometimes not. I'm able to see menu items like 'games' etc but as you move the cursor the items appear and then disappear on and off. But you can get there if you persist. I have an image of the partition (1) and can easily restore and did and tried again. The system was/is a fresh load of Mint 22 (not an upgrade) about 30-40 days ago. Been flawless since load. Like to know what can be done to get going. I have run up 22.1 off of a USB drive and see no issues. I sure want to avoid reloading again since I did it just weeks ago. Thanks.
