Hello, yeah it's related to the error spam. Can you please check if Global Reflection Probe is assigned in Enviro Sky Instance -> Components section? Please assign the one that is child of Enviro Sky Standard object or try to disable and enable the EnviroSky component. But normaly it should do that by itself automaticly. So maybe try to delete enviro folder and reimport fresh. Also delete enviro from your scene and try to resetup. Sounds like something is screwed up here.
