However, we were unable to install the simulator via the package manager due to the error shown in the attached screenshot (we tried both Mac OS and Windows OS). We will need support to resolve this error and work further.
Thank you for the update @sudha.sandhiya. I could only reproduce the error when I switched my wi-fi off, so wanted to check that first.
The best way forward is to please send us the error log within ML Hub: Home > Save Diagnostic Logs
You may also uninstall the Hub and reinstall it again as a next step, but we'd like to take a look at the logs too to get this resolved fastest. Thank you.
