Bricked Giga R1 Wifi?

my Giga no longer connects to the computer via USB.
Windows 10
went into device manager, and there is no serial port for it there. it was previously working just fine, now it is not.

i had changed the serial port to work with software i was trying to use with a sketch. after the serial port number change, it no longer works.

never mind... it suddenly popped up in device manager...
it works now, with no idea what i did...
