Also, if the PCB isn't too complex, you could try reverse-engineering it, draw a schematic and trace a PCB yourself. Then order it from some cheap prototyping PCB house like JLCPCB, PCBWay or many others, look them up. Or try etching one yourself if you're up to a weekend challenge.
That way you would have some spare boards already made for future problems or anyone else with the same problem could get your PCBs.
