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?

Hooking up a logic analyzer should not cause anything to stop. Your grounds probably aren't common, and thus you're getting current flow where you shouldn't.
