[Mac OS BigSur] FSLeyes: Unable to load OpenGL library

Recently, I updated my Mac OS from Mojave(10.14.6) to Mac OS Big Sur (11.4). In doing so, I am unable to open FSLeyes in AxonDeepSeg

I get the following OpenGL issue: Unable to load OpenGL library. Log is below:

Here was the solution I think: https://stackoverflow.com/questions/63475461/unable-to-import-opengl-gl-in-python-on-macos

This solution works amazingly well.
