Hello,
Sorry to hear you are having issues. This is weird, I never saw this thread before today, However, I also have same Windows 11 version as yours. And on Start11 v2.03, yet I do not see that popup ever. Have you try, uninstall Start11, reboot immediately after, re-download the latest version again. Reinstall it and reboot again. Retest and report back.
Thank you,
