After running my project with debugger my breakpoints become this grey sign. I allready tried several things:

• clean everything
• invalidate caches
• restart everything

How can I find out whats wrong with my project?

• Dart 3.7
• Flutter 3.29.1
• Android Studio
• Dart Workspace

It's also not working with breakpoints in VS Code, but it is working with breakpoints directly in dart dev tools.
