Have you tried plugging a guitar cable to connect the From Effects to the Send Effects loop? Dirty contacts on those jacks can weaken or cut out the guitar signal. Just a thought to try it first to get that one out of the way.

Almost certainly a bad master pot or a ground fault where the master is grounded. That should be an easy fix. There can be a lot of stress where pots mount, so check for lifted pads or broken traces on the board there.

Hey, don't get stressed , everything can be repaired.

You already did one part, now continue with the next, be it dubious loop jacks or a problematic pot ... or anything else.
