upgrade to 5.1 caused paint.net to not work anymore

[mtg828]

Paint.net had been working great for me. I upgraded to latest 5.1, and now it doesn't work.  The screen loads, but seems to freeze, no task bar, can't shutdown, can't move the window.  pallets are all just white.  I've tried uninstalling, deleting all paint.net folders and clearing paint.net reg entries.  I've tried the portable install as well as the offline x64 and regular (anycpu).

 

Using windows 11 on a Dell XPS laptop, fully updated with windows updates.  this is only app on my laptop that has this issue. 

 

I'd like to go back to previous version, but those older versions don't seem to be available any more.

 

Any idea's of what could be issue?

Sounds like you use Sentinel One antivirus?
