What happened?

When using audio-reactive-led-strip to send LED data over UDP the ESP32 reboots after about 10sec of streaming with the following message:

Running 75e857a5104c4c0b0c9761e69c8cb154cedb3320 with the following PIO config as suggested here https://github.com/Aircoookie/WLED/issues/3637#issuecomment-1875120887

extends = env:esp32dev
monitor_filters = esp32_exception_decoder 
build_flags = ${common.build_flags_esp32} ${common.debug_flags} -D WLED_RELEASE_NAME=ESP32_debug

To Reproduce Bug

Run visualisation.py from https://github.com/scottlawsonbc/audio-reactive-led-strip Update config.py with the correct IP and UDP port.

Expected Behavior

Should run without crashing.
