Description of the bug

There's error message after running the following code.

maxwell = Maxwell3d( version="2023.2" )
maxwell.release_desktop()

maxwell = Maxwell3d( version="2024.1" )
maxwell.release_desktop()

However, it's ok when I reverse the sequence.

maxwell = Maxwell3d( version="2024.1" )
maxwell.release_desktop()

maxwell = Maxwell3d( version="2023.2" )
maxwell.release_desktop()

Steps To Reproduce

Run the following code.

from ansys.aedt.core import Maxwell3d

maxwell = Maxwell3d( version="2023.2" )
maxwell.release_desktop()

maxwell = Maxwell3d( version="2024.1" )
maxwell.release_desktop()

@RickKuKu It is weird, could you put a time.sleep() ? Maybe the process is not killed and the OS needs a time to kill everything.

You should even be able to open in the same script multiple desktops using this setting:
settings.use_multi_desktop = True

I would also use GRPC by default:

settings.use_grpc_api = True

@Samuelopez-ansys Thanks! It works when I use the setting "settings.use_multi_desktop = True".
If I set "time.sleep(5)" and "settings.use_grpc_api = True" without "settings.use_multi_desktop = True", it can't work.

If I open version 24.1 first and then open version 23.2, it can work even with the setting "settings.use_multi_desktop = False".
Is it an expected result?
