This shows that the 3rd chain is dead, in the op it was chain 0 ( labeled 1 in the GUI), did you swap these two hashboards?
Yes he did that was my suggestion on my
previous post to know if the cable is damaged or the hashboard is dead.
I don't see any strange logs except on the abandon mix board and 0 ASIC on the 3rd hashboard.
If we see these logs like the Abadon mix board the first thing that comes to my mind like Philipma1957 said that 3rd hashboard might be a replacement board which is why it stop mining due to the EEPROM compatibility issue.
About the OTG SanDisk, that thing might work but I'm not sure if the s19j pro USB port support USB 3.0 and it's a bit expensive why not just buy a Micro USB port to USB female connector which is cheaper if you already have a USB flash drive.
