RuboCop version

Failed, but it's:

ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux]

And RuboCop updating from 1.32 to 1.35: https://github.com/AlexWayfer/alt_memery/pull/57/files

What does git status --ignored --porcelain return? (If you don't want to share it on github take a look at it). That seems to be line 34 so something in that line is not being parsed by YAML properly.

!! .benchmark.rb
!! .test.rb
!! Gemfile.lock
!! coverage/
!! node_modules/
!! package-lock.json
!! pkg/
!! yarn.lock

As you can see, it's completely open-source project.

Yep, it seems like ERB. Supported by RuboCop. But, I guess, something got broken with Ruby 3.1 and Psych 4.0, where parsing became more strict.
