Installed crossbar.io using pip install crossbar in Windows 10 and python 3.7.
From cmd, run the following commands:
crossbar init
crossbar start
But the router does not start. The error logs are as follows (full logs here):

Note: What I'm actually want to achieve is posted here. I found crossbar and autobahn might be useful. To use them for my context, a router is required.
What I missed? How to start a router without the docker?
