PyCharm Professional 2024.3 not stopping at breakpoints

Same problem. I've just downloaded fallback version 2024.2.5 and debuger stops at breakpoints normally.

There are more details on my case.

PyCharm 2024.3.1 (Professional Edition)
Build #PY-243.22562.180, built on December 11, 2024

Current Desktop: ubuntu:GNOME

I use docker + SSH remote interpreter.

When I run project in debug mode in 2024.2.5 I see on console next

import sys; print('Python %s on %s' % (sys.version, sys.platform))
ssh://root@127.0.0.1:9101/usr/local/bin/python -u /root/.pycharm_helpers/pydev/pydevd.py --multiprocess --qt-support=auto --client 127.0.0.1 --port 59857 --file /app/manage.py runserver 0.0.0.0:8000
Connected to pydev debugger (build 242.24807.21)

But when I run debug in 2024.3.1 then I see next

import sys; print('Python %s on %s' % (sys.version, sys.platform))
/usr/local/bin/python /root/.pycharm_helpers/pydev/pydevd.py --multiprocess --qt-support=auto --port 29781 --file /tmp/pycharm_project_323/manage.py runserver 0.0.0.0:8000 

There is no message Connected to pydev debugger (build 242.24807.21)

That what I found in log file

2024-12-22 17:44:53,183 [2129487]   WARN - #c.j.p.d.p.t.ClientModeDebuggerTransport - [2058103262] Handshake failed

If I connect to docker container and try to run next command then nothing happens.

/usr/local/bin/python /root/.pycharm_helpers/pydev/pydevd.py --multiprocess --qt-support=auto --port 29781 --file /tmp/pycharm_project_323/manage.py runserver 0.0.0.0:8000 

But if additionally --client 127.0.0.1 is used then I got 

Could not connect to 127.0.0.1: 29781
Traceback (most recent call last):
  File "/root/.pycharm_helpers/pydev/_pydevd_bundle/pydevd_comm.py", line 467, in start_client

I hope that this will be fixed in new version after holidays. As for now I just have to rollback to 2024.2

sudo snap info pycharm-professional
sudo snap switch --channel=2024.2/stable pycharm-professional
sudo snap refresh pycharm-professional

Also I mentioned that add new interpreter UI was changed. So, I suppose that in 2024.3 developers broken something.
