Hello @xakep71k, this issue should be mentioned to the game's dev(s) if it hasn't been already.
From your log, these look like some lines of interest:

[Crash] Error in gl_render_device/gl_shader.cpp:238, build (no build identifier)

Assertion failed: bi.variable_index != -1

The local shader constant `inv_input_texture` in program 101 was not found in it's constant buffer.

There's some near-match forum posts that hint that this kind of issue could be video driver related, and the game's system requirements suggest that Intel GPUs are not supported. That said, it might be worthwhile to also mention your experience to your video driver vendor for them to ponder as well.
