Integrated graphics are well known for being puny, so it comes with no surprise it doesn't work.
You should upgrade to a machine with a dedicated GPU.
Archicad 21 has a minimum requirement of OpenGL 2.1, but needs OpenGL 3.x for full leverage. It seems that while in theory the Intel graphics could provide that, they cut down the driver. So try to update the driver first. Otherwise there are also some kind of hacks to achieve that. Good luck!
