Hello Dhruvin, can you tell me if the tool has been released officially? I mean, this video is from February 2021 so probably something more reliabile has been developed, do you have any reference?
For future reference: make sure you unzip the Tooling Files and run the build.cmd from a local folder. I saved it to Documents but apparently this is synced from and syncing to my Office365 OneDrive making it a cloud folder which the build.cmd does not like... I did everything from my Downloads folder with success 👍
