      Im having the exact same issues here - as soon as I start ending data, the ESP board give me this:

      Guru Meditation Error: Core 1 panic'ed (Interrupt wdt timeout on CPU1)

      and reconnects, then the LEDs change as they should for a split second, and the same thing happens...let us know if you find a solution and ill do the same here.

        So Im a little but further, I solved the issue with the WIFI dropouts / ESP32 resets. I had a different version of FASTLED library installed. Be sure to use the one from here:

        I am now get really poor framerates however, so Ill have to dig in a little deeper...but at least the connection is stable.
