unity windows show up , but remains blank

[husphone4321]

so i am trying to get tdw-transport-challlenge working. I have followed the instructions to download the build for tdw1.8.7. Everything seems fine, and then i execute the following code from the tutorials:

from tdw.controller import Controller
from tdw.tdw_utils import TDWUtils

c = Controller()
c.communicate([TDWUtils.create_empty_room(12, 12),
               {"$type": "create_avatar",
                "type": "A_Img_Caps_Kinematic",
                "id": "a"}])

the unity windows shows up, but it remains black inside. Any idea why? I am running on a regular laptop with no nvidia gpu.
Here is my console output:

C:\ProgramData\anaconda3\python.exe D:\unity\tdw-transport-challenge\tdw_transport_challenge\test4.py
