See dtolnay/anyhow#250 and therefore rust-lang/rust-analyzer#12973.
The solution is to delete the src-tauri/target folder and run cargo check inside src-tauri/ befora rust-analyzer can run (you may need to close the editor for that, not sure how it works).

Super annoying but there's nothing we can do about it :/
