Trying to Update or Install new Apps but it always gives Error Code 191?

Hey!

Today I tried updating my Creative Cloud Desktop but it said ErrorCode 191. So I thought "Ok lets skip this and try installing XD". Well... when I tried that, I got the same error but with an option to see the error log easier. In the error log it said: 

Exit Code: 191
-------------------------------------- Summary --------------------------------------
 - 2 fatal error(s), 2 error(s), 0 warnings(s) 

FATAL: Error (Code = 191) executing in command 'AddUWPAppxCommand' for package: 'UWPAssets', version:23.1.32.2
FATAL: Error occurred in install of package (Name: UWPAssets Version: 23.1.32.2). Error code: '191'

 The german part in the end says something like "Windows can't install the APPX Package Adobe.CC.XD_23.1.32.2_x64__adky2gkssdxte on the volume H:, because it isn't supported by the filesystem".

The thing is, I don't have any Adobe products or install folders on the volume H:, so why does it want to install something there?
