Hi @Sean Liming Greetings! Thank you for bringing this issue to our attention. I could replicate the same issue locally using the using the GUIX studio clone option. I will check with the team and get more information on this error.
In the meantime, you can download the repository to your local directory through GitHub bash prompt using the command
gh repo clone azure-rtos/guix or download the repository in the Zip format from the following URL - Download GUIX Master
After cloning the repository to your local directory, you can click Configure in the GUIX studio, choose GUIX repository and select the option I have already cloned the GUIX repository, let me select the local directory. This will allow you to open and load the projects provided in the samples directory of the repository in the GUIX studio.
Hope this helps you get past this error. I will update the response once I get more details on the root cause.
