I get the same issue. When I try to troubleshoot by setting lsp-log-io to t, the server does not immediately crash. Instead, I get an error LSP :: Error from the Language Server: waiting for cargo metadata or cargo check (Unknown error) and then it hangs.

Me either with exactly same log reported by @patmryan, and it succeed to connect from time to time. Strange. 🤔

i'm also having this problem. is there a way around, perhaps running rust-analyzer locally rather than remotely?
