manimgl 1.6.1 doesn't work with PyOpenGL 3.1.7

[ludalevy]

manimgl 1.6.1 doesn't work with PyOpenGL 3.1.7.
When I'm trying to run the example, I have the error:
/OpenGL/error.py", line 230, in glCheckError raise self._errorClass( OpenGL.error.GLError: GLError( err = 1280, description = b'invalid enumerant', baseOperation = glBlendFuncSeparate, cArguments = ( GL_SRC_ALPHA, GL_ONE_MINUS_SRC_ALPHA, GL_ONE_MINUS_DST_ALPHA, GL_ONE, ) )
It meant that GL flags are NOT supported. I checked.... the flags are compatible with very old PyOpenGL version.
My Python packages:
