I downloaded the trial version of V-Ray5 for SketchUp. The Light Gen doesn't generate the thumbnails. It's just staying blank. Chaos Cosmos also is not working. I tried to download some assets, but it's loading 85%-95% and then freezes. I'm using SketchUp 2021. Windows 10, 64-bit AMD Ryzen 7 3800X 8-Core Processor 3.89 GHz RAM 32.0 GB What is the problem?
