Repairing broken trace on commercial board
Flexible wires is probably one of the safer options.

Conductive epoxy exists but seems overkill here.

Silver filled track repair compound exists - expensive, somewhat fiddly to use (doesn't conduct when wet - needs material to dry and settle for silver particles to make contact)

Copper tape with adhesive backing exists. Used for window tapes for alarms and fake leadlighting as I recall.

I'd try flexible multistrand wires. Fasten connector in place with adhesive of your choice and run wires from connector to suitable points. You could probably have wires long enough - a few 10's of mm - to run them from a USB connector to the PCB without the two being joined.
