Please try the following:

- unsubscribe from all mods in BOTH the Steam Workshop and the Paradox mod site mods.paradoxplaza.com
- delete the folder Documents/Paradox Interactive/EU4/mod/
- delete the file Documents/Paradox Interactive/EU4/mods_registry.json (if present)
- delete the file Documents/Paradox Interactive/EU4/launcher-v2.sqlite (if present)
- run the game up and check the launcher is okay with no mod or other errors
- 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!

We are seeing a bit of that unfortunately, with no real idea what is recalling that non-existent mod. It doesn't seem to be help in the launcher, Steam or the file system!

This is a stab in the dark but what happens if you search your registry for that mod? OR if you have access to another machine, can you do a test install and see if it appears there?
