Hello,
Sorry to hear you are having issues. Please 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.
See if you see this option under your Start11 configuration setting.

If you don't see it, we need more information on your system.
- Windows 11 full version and OS Build number.
- Do you have any other Start11 version install previously?
Thank you,
Basj,
Stardock Community Assistant.
