Fences runs fine on my Win 11, once in a while explorer does crash but I don't even know if Fences is the cause.
I'm gonna take a wild guess, and say it's Fences not playing well with Win 11, but, I'll reload it and see for myself. This time around, I did a clean install of Insider Dev Channel edition of Win 11, last time, it (Win 11) just installed over my clean install of Win 10, now granted, according to the Insider Program, my CPU is not supported, but still, I'll try it.
