I just ran into this same issue. The problem apparently comes from Psych 4.0.0 which makes Psych.load refuse to load untrusted data. (See the pull request Use Psych.safe_load by default #487)

Rails addresses this , but not until 7.0.2.4

You can restrict psych in your Gemfile:

gem 'psych', '< 4.0.0'

and then a normal bundle update psych probably resolves the issue (or you might have to update other gems as I did due to versions which required psych >= 4.0.0)
