I have a Python script which open and start measures in CANoe.
It already opens CANoe but I get the COM error:
Exception has occurred: com_error
(-2147352567, 'Exception occurred.', (0, None, None, None, 0, -2147467259), None)
File "C:\Users\randomuser\AppData\Local\Temp\gen_py\3.8\7F31DEB0-5BCC-11D3-8562-00105A3E017Bx0x1x55.py", line 538, in Open
return self._oleobj_.InvokeTypes(7, LCID, 1, (24, 0), ((8, 1), (11, 17), (11, 17)),config
File "C:\SMP\S_T\Py\ST.py", line 36, in Load
self.App.Open(cfg)
File "C:\SMP\S_T\Py\ST.py", line 141, in <module>
app.Load('CANoeConfig\PythonBasicEmpty.cfg')
Do you know how to fix that?

I tried deleting an automatically generated file (enter image description here), but it did not work.
