Material Editor OpenGL 3.1 Crash on Load (model rendering works)

Essentially, it opens the window, doesn't allow any clicking within it and the whole program closes without an error message about 3 seconds later.

Start by reproducing the crash when loading the Material Editor with OpenGL 3.1 and inspect the available error output or logs, since the report says the window becomes unclickable before closing. The fix is complete when the material editor loads successfully, remains interactive, and model rendering continues to work.
