Have you installed the 2022.1.1 Update yet? ABOUT command will confirm what you have installed. If not, get it from your Autodesk Account Page here https://manage.autodesk.com/cep/#products-services/updates
Restart your PC afterwards.

If that did not help... Set GFXDX12 variable to 0 (that's a zero) then restart AutoCAD/LT2022: reverting to DirectX11 fixes similar problems for most users.

If you cannot get into the program at all do this to start it up https://knowledge.autodesk.com/support/autocad/getting-started/caas/simplecontent/content/starting-a...

Also consider turning off LINESMOOTHING and LINEFADING variables: if still no relief then start GRAPHICSCONFIG command and change the 2D Display Settings pulldown from "advanced mode" to one of the other choices.

If all else fails, then turn off Hardware Acceleration as a last resort, and start a support ticket through your subscription portal as explained here https://knowledge.autodesk.com/customer-service/account-management/users-software/support-options#:~....
