Renaming custom folders in This PC

Question

I have two custom folders in This PC, one named TV Shows A-K and the other named TV Shows L-R. These were created using Winaero tweaker. I need to rename these. I cannot access this section of Winaero Tweaker to delete previously created custom This PC folders (I can create new custom folders- just can't delete existing ones) due to a problem with my Windows 11 Pro installation- the existing folders won't show up in Winaero Tweaker due to an exception error, so I can't see them in Tweaker to delete them. (I know this problem is in Windows and not Winaero Tweaker. I have already tried reinstalling Tweaker and doing an in-place Windows upgrade).

Does anyone know how I can either delete these existing folders, so I can create new ones in Tweaker, or know how I can rename these existing folders in either the registry or some other way to the new names?
