System configuration
Rails version: 7.2.0-alpha
remote: https://github.com/rails/rails.git
revision: 284baa18c2c62abec170b61e285aefbd9604f675
branch: main
Ruby version: ruby 3.3.0 (2023-12-25 revision 5124f9ac75) [x64-mingw-ucrt]
Fix
The issue is fixed by installing binstubs for rubocop (unfortunately, right now, I do not know where the fix would be applied in the Rails codebase).
$ bundle binstubs rubocop --force
If you point me to where it should go, I am happy to open a PR. Else, I'm happy for someone to do this at the correct place. Thanks!
