PyCharm does not stop in debugging mode at the breakpoints in a QThread

PyCharm does not stop in debugging mode at the breakpoints of a piece of code launched by QThread on a new installed station with fresh fedora core 37 and pycharm-community-2021.3.2 or pycharm-community-2022.3.2 or pycharm-community-2023.2.2. Breakpoints work very well for methods in the same module before QThread is used. That's why I thought of a link with QThread.

It worked fine on an old fedora core 33 station with the same codes.

After spending many hours trying to fix the issue (I consulted everything I could find on the subject for example: https://intellij-support.jetbrains.com/hc/en-us/community/posts/203420404-Pycharm-debugger-not-stopping-on-QThread-breakpoints) I have just installed LiClipse and launched it without reading the documentation with the default configuration and it works perfectly ... The problem seems to come at least in part from PyCharm!

Maybe I'm missing something?

I'd got into the habit of using PyCharm and find it a good ally for development, but if I can't use debugging I'll have to switch to another IDE. I'd be very sad about that.
