Hello,
Sorry to hear you are having issues. But, I can not reproduce your issue on my system. I am on Windows 11 v24H2 OS Build 26100.6584 and Start11v2.55.

Would like to suggest to try, uninstall Start11, reboot immediately (important), download latest 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,
