Please try the following:

- unsubscribe from all mods
- delete the folder Documents/paradox/Stellaris/mod/
- delete the file Documents/paradox/Stellaris/mods_registry.json
- delete the file Documents/paradox/Stellaris/launcher-v2.sqlite
- subscribe to a few mods
- in the Steam betas tab for this game opt into the "stellaris_test" version which is 2.8.1
- run the game up and see if those mods are now available to you.

I hope that does it for you!

Does this happen with every single mod you try? Or just one or some?

Are these mods from Steam, our mod site, or local?

If Steam or our site, do they physically end up in the Documents/paradox/Stellaris/mod/ folder?
