Check data length before sending or increase RX buffer size, but this can be done only in library IIRC.
Another thing is to reconnect when this is happening.

As far as I can tell I did not see any log about a stack overflow. It is in there, just it is a bit masked because of guru: I (320) example: Using SDMMC peripheral ***ERROR*** A stack overfloGuru Meditation Error: Core 1 panic'ed (LoadProhibited). Exception was unhandled. <--- STACK OVERFLOW Core 1...

I have thiis adapter connected in breadboard and 5V of course, and from time to time im having err 107 or 108 dont remember now. Its enough to move adapter a bit for better connection.

This may be problem with sd card, esp32 can be picky about sd cards.

You have to find out which task is short on stack, that probably will solve guru meditation crash.
