Until https://github.com/rust-lang/rfcs/issues/721 is supported, you will have to use WSL/WSL2 or use the windows long path hacks like \\? and setup windows long path support which still does not work in most cases.
I am trying to integrate RustAnalyzer with a tool I wrote to handle long paths for me on windows which uses a process hack https://github.com/sumukhballal/cargo-winpath-redirect. If I have any success, I shall keep you updated.
