My file is showing the error Crash #710628
The crash looks like it happened while extensions were loading.
I checked for other people who had the same crash. There were quite a few with SketchUp 2023, only a couple in 2024, and a moderate amount in 2025. Nobody seems to have had the problem in SketchUp 2026.
Are you able to give 2026 a try?
If the problem happens with a particular file, can I try the file?
