Unity hangs while trying to build the example scenes. It gets stuck on 'Building scene 0: HelloAR'. I tried with the Hello AR scene and the PersistentCloudAnchors sene. Unity hangs and I have to force quit. No errors or messages in the console at all. I was able to build the persistent cloud anchors scene on a Windows 10 machine and with AR Foundation and the ARCore extensions package on the same mac osx machine.

Open the Persistent Cloud Anchors or Hello AR scene and try to build.
After retrying several times, it is now working. I have no idea what changed as I did nothing differently which is a bit scary. Maybe the package has been updated.
