Hi @ayush-kumar-423, would it be possible to have to whole list of installed packages? With pip list. This is most likely an incompatibility issue. I was not able to reproduce for Ansys 221 on a Linux machine with Python 3.10 and the package versions as listed in the picture.

>>> server = dpf.start_local_server(config=dpf.AvailableServerConfigs.LegacyGrpcServer, ansys_path=r"/XXX/v221")
>>> server.ip
'127.0.0.1'
>>> server.version
'3.0'
>>> server.shutdown()
Killed

Would it also be possible to test if the problem persists with ansys-dpf-core==0.7.2?

Hi @PProfizi, I have updated the packages list in the description. I have asked customer if it is possible to test with 23R1.
