I would guess this is rust-lang/rustup#988, where e.g. rust analyzer runs at the same time you run a cargo command after updating the toolchain file. If it's not that please open a new rustup issue

The workaround is to uninstall the toolchain and reinstall it, usually stopping rust analyzer or similar while you're doing that
