Hello,
Sorry to hear you are having issues. Not sure why, today I also have Windows 11 version 22621.2215 on my system, which I though was insider preview release. Anyway, your issue not appearing on my system. So please try this, uninstall Start11, reboot immediately (important), reinstalled Start11, reboot immediately again. Retest and report back.
Thanks
