Sketchup 2024 taking hours to open/load

[Nguice]

I've been having a problem with 2024 (Windows 10) over the last few days where it will open the welcome window with no problem, but when I go to open a new or existing model, it will show a blank white screen with (not responding) in the upper left corner which will persist for hours before it finally loads. Once loaded it seems to work fine, I can even open other models within that same session with no problem, but when that window is closed, it will have the same issue with the next time Sketchup launches, or if I open a second instance that session too will do the same thing.

Last week on Friday I installed the SketchFx 4.0 Demo and tried it out on something for marketing. I didn't notice any other issues that day with Sketchup. When the issue started, since that was the last thing I'd installed, I deleted the plugin and uninstalled it from Sketchup. The problem still persists, so I've uninstalled and reinstalled Sketchup 24 and it's still happening. I've seen a reference to COM Surrogate issues, but ending the task in task manager has had no affect.

I still have previous installs of SU20 thru SU23. I've only tried 23, and it still opens and runs just fine.

Is there anything I'm missing that I should try?

What graphics card? Which graphics engine is selected in Preferences>Graphics? Try the other one. Since this just started happening you have to look at what has changed on the computer. SketchUp 2024 hasn't been updated recently so what was? Graphics drivers? Maybe try updating the graphics drivers direct from the source. Don't trust Windows to tell you if the drivers are up to date.
