使用最新Ruby/Debug gem时Rails应用调试冻结问题求助

问题现象 #

• 使用thor调试应用一切正常，但通过rails server启动调试时，Web应用请求会一直运行直至超时，即使把断点设置在无问题的首页也无法正常触发调试
• 用相同Ruby/Rails版本创建的全新Rails应用，调试功能完全正常，排除基础环境问题

临时可行方案 #

目前通过以下命令使用Chrome DevTools可以正常调试：

rdbg -n --open=chrome -c -- bin/rails s

但使用VS Code调试时仍存在相同冻结问题，这只是临时解决办法，并非根本方案。

问题推测 #

推测问题源于gem冲突，或者application.rb/development.rb中的配置异常。

应用背景 #

该应用为多年前创建，已持续升级至最新Ruby和Rails版本。

环境信息 #

• Ruby版本: 3.3.3
• Rails版本: 7.1.3.4
• Rdbg版本: 1.9.2
• 操作系统: Fedora 38

我发现并非只有我遇到这个新版Ruby/Debug gem的问题。
