Unable to boot webos emulator

I have followed the instructions on link to install webos emulator vs 3 & 4 on windows. I have also used this alternative procedure link but despite the method i choose, i just cant seem to get the emulator to boot. It’s stuck at: ‘Booting the kernel’.
Any help would be greatly appreciated

could you guide me on installing webos 4 emulator?

Please uninstall old webOS TV SDK and use webOS Studio extension. You can refer to Prepare for installation. Thank you.
