I have a script that I can confirm runs on other people's computers, but not on mine. Instead, it gives this error code:

It's the product of another question I asked on StackOverflow. The person giving the code assured me it worked on their computer, but neither computer I have access to works. They either give the above error or no output (it seems random which one they pick).
I've already tried reinstalling python and all packages.
Interestingly, commenting out line 84 (self.gl.glTexImage2D(self.gl.GL_TEXTURE_2D...) gives an output, but without the wanted texture.
Possibly helpful information (will be added to as others suggest):
- Windows 10 64-bit
- Python 3.9.0
- PyQt5 5.15.2
- numpy 1.19.3
- PIL 8.0.1
- I generally use Sublime Text to run the code, but using a command doesn't change the outcome.
