Hi!
That does sound very odd. Especially the bit where you do see a couple of clock cycles before it stops. The fact that the display initially works also makes me very suspicious of the SD card part of the SPI bus... maybe there's an issue with the SPI mux that sits between the ESP32, SAMD21, and SD card? Although I'm not sure I can think of any kinds of soldering issues off the top of my head that it would cause it to fail like this.
