Could you confirm if this also happens in the default Administrator account?

Open Start
Type: cmd
Right click CMD
Click Run as administrator

At the command prompt, type:
net user administrator/active:yes

Hit Enter

Close command prompt, restart, then try signing into the Administrator account.

If it does, then the next option is to perform a repair upgrade:

What I would do at this point is wait a few days for Spring Creators Update to be released, install Media Creation Tool and choose Upgrade This PC Now. This is the most stable way to change to the newer version and because it reinstalls WIndows while keeping your files and programs in place, it fixes most problems. If not you'll know it's due to a program conflict and we can go from there.

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.

This first step fixed it. I had to reactivate UAC for some reason it was turned off.

Great! I am glad that worked! If you don't have any more questions, feel free to choose a rating and have a great day!
