The console become frozen while debugging in Rails

[jdonadob]

Your environment

• ruby -v: ruby 3.2.3 (2024-01-18 revision 52bb2ac0a6) [x64-mingw-ucrt]
• rdbg -v: rdbg 1.9.2
• rails -v: Rails 7.0.8.1

Describe the bug
The console become frozen while debugging in Rails.

To Reproduce
I set a Breakpoint in my code: 'binding.break' or 'debugger'. Next I run the Test: rails test test\system\requests_test.rb.

Expected behavior
A command prompt next to the breakpoint waiting for orders.

I have the same problem.

Debug works when I use thor on my app, but when I want to use it on my app (rails server)
it freezes.
It works also when I create a new app with the same Ruby/Rails versions.

My app is built originally some years ago and I've constantly "upgraded" it to the new Ruby & Rails versions.
It seems that there's some conflict either one or more gems and
the 'debug' gem or something wrong in my configs (application.rb / development.rb).

Some details:

• Ruby version: 3.3.3
• Rails: 7.1.3.4
• Rdbg version: 1.9.2
• OS: Fedora 38

I attach here my Gemfile, application.rb & development.rb.

Sorry I don't enough knowledge to make repro code.
