To trouble shoot further you can:

Try a SafeBoot https://support.apple.com/en-us/HT201262

Takes noticeable longer to get to the login screen as certain system caches, dynamic loader cache etc get cleared and

rebuilt. This test will tell you if third party interference; extensions etc are not loaded in safe boot mode.

Test issue in another user (or guest user) account https://support.apple.com/en-us/HT204443

This will tell you if it a universal issue or isolated to your user/admin account.
