Unexplained Panda3D Pipe Errors

[nosyliam]

I'm unable to work on a Panda3D project because of these random GL/Direct3D errors that came out of nowhere. I was testing out the project with the Panda3D SDK until suddenly I was unable to open the ppython window (I could only see the default windows border for a split-second when I tried to view it) and afterwards I was greeted with startup/init errors. Logs:

To make it even stranger, I'm able to run the game completely fine on an embedded Panda3D client. I've already updated my PC, installed the latest NVIDIA graphics drivers for my card, and uninstalled and reinstalled Panda3D. Any insights to what's going on would be greatly appreciated!

Are you able to run pview.exe at all? If not, could you please set "notify-level-display spam" and "notify-level-glgsg spam" in Config.prc, redirect the output to a file and post it here?

Somehow, deleting my game's source and re-cloning it fixed the issue. Guess it was just one of those random, unexplained flukes so I'll close the issue.
