This is a tough one, because it doesn't happen on my system but just for 2 remote testers in Russia and Poland. While for me and others it works fine. No logs produced and nothing of value in System event log. Just immediate crash since the 2019.1 alphas. 2018.3.3 and before work fine in the same systems. Tried different graphics cards and settings to no avail. Just have the screenshot of the error below. Seems to be a UnityEngine issue but again I can't replicate on my system so hard to diagnose.
