I've stopped using Xcode Cloud about 2-3 months ago because of this issue. It keeps failing randomly during the 'npm ci' or 'npm install' processes with the error 'The Post-Clone script timed out. No activity has been detected on stdout or stderr in 15 minutes.' It seems to fail at different points during the process each time. For instance, last time it failed while installing 'phin @2.9.3', and another time on 'uglify-es @3.3.9', and so on. I've resorted to using Xcode to build locally and then upload to the Apple Store, but this is quite frustrating -- we've already encountered a few bugs that were introduced due to this manual build process
