Hi there @EagleJackson. What version of Ruby is being used here? Also please ensure Ruby has been installed to a path without spaces (saw this as an answer to a similar issue).

[EagleJackson]

Ruby 3.2.2 and then I tried 3.1.4 on accident.

Check to see if RUBYOPT is set in your environment variables; if so try unsetting this.
