Not sure if this is a Sketchup 23 issue or PlusSpec as I’ve never had it happen in 22 or 21 versions of SketchUp.
Basically if I update a scene after repositioning the scene, changing hidden geometry, changing style and anything that requires a scene to be updated. If i then go to another scene tab to quickly I get a bug splat 100% of the time. If I update a scene then wait say 30 seconds to change to the next scene it almost never crashes.
That’s a really odd issue & one that I haven’t heard of or come across before.
Since all the actions that you are doing are SketchUp actions I would say that it’s likely to be a SketchUp-related issue. To confirm this, would you be able to please manually add a handful of scenes (go to ‘View > Animation > Add Scene’) & see if the issue occurs for non-PlusSpec-created scenes?
I also get this, it is a Sketchup issue, but a little birdy tells me it will be fixed in the next release of Sketchup23 . It is frustrating, to say the least.
