So I tried removing the _build folder - but it didn’t change anything.
But then - deleting .elixir_ls in the project seems to have helped on the issue. This was even one of the things that was mentioned in another post here with similar issue, so I guess I should have also tried this. As a consequence of this, I have added .elixir_ls to .gitignore in case there are some local versionings deps that other devs might overwrite.
Thank you for taking time to answer this. I expected it was very trivial.
