Started getting this today, DF v9.9, Win10 Pro. This is a new system build with a fresh install of Win10 Pro 21H2 and DF. I saved my DF settings before resetting and then imported them after I installed DF. Been running about a week.

Title bar reads "DisplayFusion.exe - System Error". DF aborts after I click the OK button.

I restart DF and after a couple wallpaper changes this happens again.

Suggestions?

This happened three or four times in a row yesterday. Then it stopped. And DF has been working okay since. I hadn't made any changes or rebooted so I'm at something of a loss.

I did a fresh install of Win10 because the previous Win7 -> Win10 upgrade had too many things that were broken or otherwise didn't work right. It seems I've just swapped one set of problems for another because things that previously worked now sometimes don't. <sigh>
