Hi Michael, thanks for sending the crash report.

Yes it looks like the video driver is throwing an assert.

I found a reference to this crash, maybe the configuration information in the post will help you to solve it:

Then yes the other thing is that it's using the Intel integrated graphics instead of the RX5700. Either the RX5700 doesn't have a driver set up or it's ordered or prioritized in some way different from a regular macOS install.
