key already exists, key: Strings.FilterAdministratorSettingsCategory

I'm using SDL Trados Studio 2021 Professional - 16.0.1.2917

I have some .string files I need to analyze and the system doesn't support that so I created one using instructions from this site:

https://gateway.rws.com/csm?id=kb_article_view&sysparm_article=KB0035271

When that didn't work I decided to just download the zip folder at the bottom of that page and import it.

When I did that, I now receive the error: key already exists, key: Strings.FilterAdministratorSettingsCategory

I can't open the File types at all now and when I create a new project and click on File types, it throws the same error and shuts Trados down completely. I know there are 2 instances of the file type .strings in there now, but how do I get this working again?
