As the title says, and a few Reddit threads I came across. There is some issue with the firmware on the U80-A PCB, at least the SEQ 2 Hotswap version maybe more I haven't tested my solder ones yet, where intermittently the keyboard becomes completely unresponsive to any computer I connect it to, macOS or Windows. Refreshing it with the firmware directly from the VIA website in QMK Toolbox will temporarily fix the issue.
