Hello, I had the same problem as you and tried lots of methods hoping it would be fixed. I even tried performing an in-place upgrade but the bug remained. However, due to frustration, I decided to find registries of the Quick Action Menu and managed to fix it.
Perform it at your own risk.
This fix required you to remove registry keys and it might not work on your device so first, I would like you to backup (export) the keys "Quick Action" under HKEY_CURRENT_USER\Control Panel\ by right-click on it, select export, choose a safe location and give it a name then press OK.
After that, simply delete the key "Quick Action" under HKEY_CURRENT_USER\Control Panel\ and restart your device. It should work but it might be a bit buggy at the beginning, you should wait a bit and if the unresponsiveness is not gone, give it another restart.
If anything goes wrong, simply locate the .reg file I asked you to save earlier, press on it and press YES to restore the key to the state before you tried my method. Hope that helps.
