Thanks for the suggestion Laura_D, I did try building an example project and it did build.
But when I used my project, it failed with the scenario I described above. Is it due to the project size, timeout or if there are some changes applied recently that might cause the issue?
The issue did not occur until yesterday, and its very frustrating as I need to build apks for myself and my team to test on devices as we are doing a mobile game.
Are there any people other than Ashley who might be able to look into the situation?
Greatly appreciate your time and help.
