After a lot of experimentation, I have determined that this problem is intertwined with the AMD Ryzen USB issues that have been getting more and more press (see: https://www.anandtech.com/show/16554/amd-set-to-roll-out-agesa-firmware-usb-fix-for-ryzen-coming-april)
I have determined that the problem does not occur when using a powered USB hub, at least with the one I have. I have ordered another to test with. I still believe that this issue also lies within the QMK code for STM32 as the behavior does not occur on AVR-based boards however this firmware update by AMD referenced in the attached article may resolve the issue as well.
VIA freezes on a keyboard designed around the STM32F072 CPU (TKC GodSpeed75) when used in conjunction with the USB hub designed to fit it, our custom TI 8020B USB 3.0 hub.
