pycharm debugger not connecting: KeyboardInterrupt

Question

Somehow my pycharm debugger doesn't connect anymore.

I tested all ENV. Also, reading up on it on stackoverflow: I deleted the .idea directory.

However, after restarting the pycharm .idea is always recreated (deleted caches and even deleted&downlaoded pycharm again)

I had similar problem. I have removed (remove, not disable) all existing breakpoints (in the dialog box invoked by Ctrl+Shift+F8). After removing all breakpoints and modifying run configuration (disable add content roots and add source roots to PYTHONPATH) debugging started to work. Enabling them back and still working fine - problem gone.

I think that removing breakpoints will be sufficient to solve the issue. See hint from JetBrains community: https://intellij-support.jetbrains.com/hc/en-us/community/posts/115000014004/comments/115000239630
