I am having the same problem.

Got this solved by first uninstalling bcrypt with gem uninstall bcrypt, then bundle install (or gem install bcrypt).

I've got the same issue but couldn't resolve it with your tips...

I'm not sure if this will solve the issue for everyone, but when I was doing some searching, I ran across someone having a similar issue on protocolbuffers. They mentioned that the error was related to the gem missing the arm64 binaries for the extensions.

I ran gem install bcrypt --platform=ruby and was able to use the BCrypt gem without issue in my test rails app and in rails console.
