I’m using Spyder through WSL2 (miniconda installed through Linux) and the debugger isn’t recognizing breakpoints.

Upon starting a Spyder kernel in the Linux terminal with python -m spyder_kernels.console --matplotlib="inline" --ip=127.0.0.1 -f=~/remotemachine.json &, the following is printed to the console:

Debugger warning: It seems that frozen modules are being used, which may
0.00s - make the debugger miss breakpoints. Please pass -Xfrozen_modules=off
0.00s - to python to disable frozen modules.
0.00s - Note: Debugging will proceed. Set PYDEVD_DISABLE_FILE_VALIDATION=1 to disable this validation.

After connecting to this kernel in Spyder’s IPython Console and trying to debug a simple program, I find that the the debugger does not detect breakpoints.

If I instead start a Spyder kernel with

python -Xfrozen_modules=off -m spyder_kernels.console --matplotlib="inline" --ip=127.0.0.1 -f=~/remotemachine.json &

the issue with the debugger persists. Any suggestions on how to proceed? Apparently a related-issue has been widely-discussed and the solution seems to have been installing Python 3.10.xx instead of Python 3.11 or Python 3.12. I tried this to no avail – alas, I still cannot set breakpoints on Spyder.

Surely someone has come across a solution to this problem.
