Remote Debug (server) Pycharm 2021.3.3 does not stop at breakpoints

The following (simplified) code used to run perfectly well a week or two ago. Now, it does not stop at breakpoints. The code runs and finishes, but the red breakpoints are ignored. Pycharm updated recently which I guess has something to do with that. It also asked me to update my pydevd-pycharm, after updating the warning was removed but this problem persisted.

python3.8

pip freeze:

certifi==2021.10.8 
numpy==1.22.3

pandas==1.4.2

Running doesn't stop, but prints:

Use the following code to connect to the debugger:
import pydevd_pycharm
pydevd_pycharm.settrace('localhost', port=12345, stdoutToServer=True, stderrToServer=True)
