[SOLVED] VS code Rust analyzer extension. Failed to discover rustc source for sysroot

full error:

Failed loading rustc_private crates for workspace 'path to Cargo.toml in workspace': 
Failed to discover rustc source for sysroot.

This error occurs in all projects even newly initialized.

rustc --print sysroot prints path

I tried to setting path manually in system variables(I'm on Win11), didn't help. Then I reinstalled all rust dependecies, restatred VS code, didn't help, resterted PC, didn't help. Again, after reinstallation via commands everything is fine: rustc and rust-src exists, rustc --print sysroot prints path. Only extension is complaining.

After I set the environment variables correctly as @Chayim Friedman said in the commments:

RA_LOG_FILE='C:\435fhdjkh84.txt' and RA_LOG='project_model=debug' (Single Quotation Marks in both variables are only for better readabilty). And created 435fhdjkh84.txt file in the path, I relaunched VS code.

And here are the contents that were written into the file specified:
