New patch from Hoyo for ZZZ (1.0.1) seems to fix the Unity crash issue. This should work for Intel integrated graphics users. I added a note for my HoYoPlay launcher version - I thought it might be related, but it's not.

Alternatively, you can find the UnityPlayer file and other 1.0.1 installation files here:

Additional notes:
apparently this will work with the "-force d3d12" shortcut
