Hello,
Sorry to hear you are having issues. But, this is what I get on my Windows 11 V25H2 (OS Build 26200.7623) system. Notice that the Start appear away from the actual Start button, clicking on it should not be an issue. I am on Start11 v2.6

Moving forward, to see if there is issue installing the app. 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.
If the issue still appear, we need more information.
- Windows 11 full version and OS Build number. Please use Winver.exe.
- Start11 full version installed.
- Post screenshot or video showing us your issue.
Thank you,
Basj,
