Unity 2020: Can't add new Tag in Editor

Hi guys,
when I try to add new tags nothing happens but a NullReferenceException pops up. A costum tag I created earlier is still there, I can delete it, but it is not possible at all to add new costum tags…

This is the error message:

NullReferenceException: Object reference not set to an instance of an object
