macOS and Sketchup 2021 - Freezing while exporting as pdf

I have SketchUp 2021 and a MacBook Pro from 2020 with macOS Big Sur 11.4. I have a lot of problems with this combination anyway as it crashes constantly. But now the software freezes, when I want to export a file as a pdf.
I tried updating SketchUp to version 21.1.278, but it didn’t solve the problem. Any suggestions? I have a report from apple, which is 1500 pages long. So i don’t know what exact information would be helpful to solve this.

Thanks
