Are you sure it's in the OpenGL units initialization?

Can you test the Lazarus examples/openglcontrol/ demo, and see does it
crash too?

Base FPC units are part of FPC (trunk/packages/opengl/src/), they are
outside the Lazarus "OpenGL component" package. In Castle Game Engine
we're using FPC OpenGL units on many platforms, including Windows 10,
and we often test with latest FPC from trunk. And everything seems to
work cool. Also, the FPC OpenGL units did not have any "critical" change
since a long time, so I doubt something broke there.

And since you already tested that reverting old Lazarus version doesn't
help, it does indicate the problem is somewhere else...
