I just updated from Sketchup 2017 classic license to Sketchup Pro 2021. I’m having great difficulties opening my files which are made in Sketchup 2017. It takes forever. While opening the program is unresponsive and eat’s up a lot of CPU and RAM but doesn’t crash and it literally takes like 20-25 minutes. Meanwhile I just see the spinning wheel. The same file opens in just seconds in Sketchup 2017.
Any ideas what might cause this issue?
