was facing the same issue, make sure that you do a "solana update" and also a rustc update. Also check that you're using an updated Node version (mine working on 17.3.0).After all updations MAKE SURE you clear cache, the command is "rm -rf ~/.cache/solana", don't remember the exact command! This is what I did to resolve the issue!
