F7 Not Booting when USB cable attached


I recently started a project with a few F7 boards and while I was able to flash one easily, the other F7 was not showing up as a USB device and now after a one-time series of blinking amber, green, and blue lights, it only briefly flashes amber when plugging in a USB cable.

The board doesn’t appear to respond to BOOT or RST with USB plugged in. Is there a way to do a hard reset or troubleshoot a problem like this?
