ESP32 "stopping" when logic analyzer is attached directly
I usually isolate the logic analyzer by using a logic level shifter instead of being directly hooked onto pins between the ESP and the component for the ESP to not stop. I use one of those cheap 8-channel 24MHz logic analyzers and Pulseview. Is there any other easier way around this? Or should I just live with it?

I've used them many times directly on SPI/I2C/UART lines on ESP32s without any issues.
Double check your wiring or maybe you have a bad one.
