@Agard From the Windows icon, press and hold the Shift key while clicking Restart. In the Windows Recovery Options menu, click Troubleshoot, and then click Advanced Options. Click "Uninstall updates", and click "Uninstall latest quality update". Hopefully that works for you.

Although Windows 11 update KB5055627 became available on April 25th, it's not currently showing up for download on my computer. I'll be sure to test it and provide feedback on this thread as soon as it's accessible.

@Andyman The app shows the Windows updates as they are needed to be installed by Windows, similar to Windows updates. If you don't see the update in the app, then it's probably not available for download and cannot yet be blocked or it's already installed and must be uninstalled. If you uninstall the update, you will need to empty the "Software Distribution" folder and restart the computer, then run the application after the restart. You will then see the update needing to be blocked.

@Dime333 I just downloaded the latest Windows11 ISO and performed an upgrade. It installed Windows11 Build 26100.1742. It installed update "KB5055523" which prevented Hyperspin from loading. I uninstalled the update, emptied the "Software Distribution" folder under "c:\Windows and blocked the update from updating in the future using wushowhide.diagcab from link above in previous comment.

There should be a “Go Back” feature in settings to revert back to previous installation. Hopefully that works for you. I’ll try fresh reinstall of windows 11 later this week to see if I have the same issues.

They should be at the bottom where it says “update history” .I wouldn’t worry about it if Hyperspin is working.

I just tested Windows 11 again. Here is the outcome Windows 11 23h2 - WORKING Windows 11 24h2 - WORKING, minus the updates I mentioned above. Windows 11 24h2 - NOT WORKING, if all updates are up to date.
