Unable to debug with Python 3.13

Question

Hi guys, as anyone run into problems with the latest TestComplete when using Python scripts?

I’m unable to debug certain files—they just won’t step through as expected.
Additionally, TestComplete is generating .pyc files, which I haven’t seen in previous setups.
This behavior only occurs when using Python 3.13 (older versions seem fine).

Is this a known compatibility issue with Python 3.13? Or is there a setting in TestComplete that needs to be adjusted? Any advice or workarounds would be greatly appreciated!

There's been a number of improvements made to Python 3.13, see https://support.smartbear.com/testcomplete/docs/scripting/specifics/python_tc_globalobjects.html which has broken existing functionality in TestComplete. This could be one of them, so it's worth opening a support ticket via https://support.smartbear.com/testcomplete/

I am experiencing the same issue. I can step only through the main file that i launched via TestComplete. I can't step into functions that are imported from another script even if its located inside the project's script folder.
Did you create a support case to discuss this issue with SmartBear?
I haven't had time do it yet since we are busy doing the migration.
