Crash During Software Update

Hey. New here.

My Mac crashed halfway through a software update of my new Kemper Player. Now it won't play ball, and doesn't seem to be able reconnect with the rig manager. I just have four flashing red lights and silence.

Any suggestions?

I'm guessing update with a USB is the first thing to try.

Still no luck here. I’ve tried a factory reset, but no success.
