If this is this an issue for you...

You can re-install the macOS on top of your existing macOS from Recovery:

Check rebooting in safe mode, it may help also takes longer in boot time compared to normal boot.

How to use safe mode on your Mac - Apple Support

Note: Safe mode prevents your Mac from loading certain software as it starts up, including login items, system extensions not required by macOS, and fonts not installed by macOS. It also does a basic check of your startup disk, similar to using First Aid in Disk Utility. And it deletes some system caches, including font caches and the kernel cache, which are automatically created again as needed.

Please check in another/new user (set up a new user account), if you have same issue.

Have ever changed your login screen before?
