Boot Camp Issues, boot loop after final setup

[gsmornot]

2017 iMac with 2TB Fusion drive running 10.15.3 beta. I can install Win10 and use it without issue until I complete the final step of running the boot camp installer in Windows. It never recovers after that loads and it restarts. If I ignore loading the boot camp installer in Windows everything works fine. I was able to complete what I needed yesterday that required Windows but thought I would keep it installed for the future. I was left booting back into MacOS and clearing the partition.

Any ideas for things I might check and do I have to install the boot camp installer in Windows? What does it do for me if everything otherwise seems to work?

Follow up. Apple device drivers will require a reboot after install. If you have anything USB C connected the reboot will fail. I had a cable with nothing connected to it plugged in. Once removed I can restart and use Windows without issue.
