Intel HD Graphics 630 reports OpenGL 4.5 but does not export necessary functions

Trying initializing OpenGL 4.5 on Intel HD Graphics 630 fails with the following message indicating that functions defined by OpenGL 4.5 Core Profile specs are missing:

OpenGL info:

  GLversion: 4.5.0 - Build 23.20.16.4973
  GLSLversion: 4.50 - Build 23.20.16.4973

  Error! OpenGL context reports version 4.5 but does not export required functions (glGetnCompressedTexImage) for 4.5

I'm having the same issue using the latest drivers for my Intel HD 630 (version 26.20.100.7000).

Much of OpenGL 4.5 is supported, but I'm unable to load some functions from 4.5, such as glCreateTextures: https://www.khronos.org/registry/OpenGL-Refpages/gl4/html/glCreateTextures.xhtml

Can we get a response on OpenGL 4.5 support? The support page states this card should be supporting 4.5.

I have the same problem as Gavrilov. It's the very first time I encounter this kind of issue. I am working with PythonOCC, OpenCascade. Any help would be useful.
