Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/CK3/mod/
- delete the file Documents/paradox/CK3/mods_registry.json
- delete the file Documents/paradox/CK3/launcher-v2.sqlite
- subscribe to a few mods
- run the game up and see if those mods are now available to you.

I hope that does it for you!

You subscribe to mods via the Paradox launcher/mod site also.
