Hello,
Sorry to hear you are having issues. If you on the latest Windows 11 24H2 updated very recently, most probably you are on the same boat with some users who reported similar issue as yours. You just need to uninstall Windowblinds, reboot immediately (important), download latest WB Beta version available in your account product download page: https://store.stardock.com/myaccount/products. Install it, reboot immediately again. Retest it and report back.
Thank you,
Basj,
