According to this page Rails 6.0 is not compatible with Ruby 3.1. This makes sense because Ruby 3.1 was released just a couple of days ago but Rails 6.0.4.4 was released more than a year ago and was the last release of Rails 6.0 since then. Furthermore, it is worth noting that Rails 6.0 is not actively maintained anymore.
I suggest using the latest Ruby on Rails (7.0.1) version when you want to start a new project. Or if you really need to work with Rails 6.0 (what I would not recommend) then you will need to downgrade Ruby to 2.7.5
