I don't know how to report this bug, but recent iso of Windows Server 2019 does not install if the Compatibility is Esxi 7.0 U1. It installs if Compatibility is set to Esxi 7.0 though with the same settings.
Trying to install with ESXI 7.0 U1 will give a driver error and everyone kept saying the ISO is corrupted, but changing to ESXI 7.0 with the same ISO worked flawlessly.
