The solution above that apple posted is not the correct solution. The problem seems like an iCloud problem to me.
IF:
- you have Catalina
- don't have general, pervasive iCloud problems (most things work, but music, or tv or podcasts.. something specific, does not)
You try to sign into music, tv, podcasts and it either accepts your password and then does nothing OR you get this error when trying to sign in: **FUSE.Error.GenericDataError**
THEN:

The correct application was posted by 'ehabjadalla' and it's buried a bit in the replies. I am reposting his fix here to make it easier:

Finally found solution without deleting your account. Thanks to Serge Rosenthaler for his reply on another post.
1) sign out of iCloud on your Mac
2) Open Terminal & use the following commands:
sudo -v
***Enter Your Mac Password***
killall -9 accountsd com.apple.iCloudHelper
rm -rf ~/Library/Accounts
killall -9 accountsd com.apple.iCloudHelper
3) restart your Mac
4) Open Music App & sign in to your account (You should sign in to your account)
5) Check your TV & Podcast Apps (You should sign in to your account)
6) Open System Preferences & go to iCloud (You should sign in to your account) just activate iCloud Drive
