I upgraded from version 3.4.1 +85781 to this preview version. After that, I opened a model in Sketchup that worked with my previous version. It was around 800MB, it took noticeably longer to load and then it refused to render, it just hung and I had to use Task Manager to close it. I tried several times to the same result. Eventually, I reverted back to my old version, and viola! it worked. Not sure why but looks like the old version was more stable and could handle bigger models.
I have an RTX 3090 with 24GB Ram as well as 128GB system ram.
