White Screen on open (by Wayne O)
Afternoon,

The program has recently not responded on opening. I'm running Windows 11, 4070 NVidia card.
Program version I have been running succesfully for over a year is 3.1 GL1, sometime last night it just didn't want to open, and I just get two white panes.

I tried all other versions - 2.3 still opens and works fine but all 3.x show me this white screen with no messages or debug. It just hangs and I have to kill it with task manager.

It worked fine, until I opened my Fonts folder. After that, any attempt to open give me a white screen.

Any tips to help me debug, or get a stack trace?

Debugging this only threw me an error when loading the dlls:

glGetError() == 0x502 invalid operation

This was happening just after winsta.dll.

On the off chance I had a bad dll, i ran SFC /scannow in cmd, but this didn't work.

I then got rid of my RecentFiles entries from the registry path (HKEY_CURRENT_USER\SOFTWARE\SolveSpace), and the program now works. It must have had a problem loading my most recent opened save.

If the problem was caused by specific model would you mind sharing it?
