debug: thread didn't start in 5.0 seconds (in state: :starting) (Listen::Error::NotStarted)

Hi, I saw the entry in Rails changelog so I wanted to try debug out in our app replacing pry. I’m on ruby 3.0.2, Puma 5.4.0, and Rails 6.1.4.1, so all the latest versions. I’m getting this error when starting rails server:

I cleared bootsnaps cache, tried loading latest version of this gem directly from GitHub, but nothing seems to make it work. Of course, binding.b are just ignored since the thread didn’t start correctly.

Any ideas?
