WLED: SyntaxError and sometimes a reset when changing presets in 2D.

What happened?

I made an illuminated sign for the back under my jersey for my favorite club.

There are 540 LEDs arranged irregularly on the sign. I configured WLED so that I use this in a 2D Matrix. When I choose a presets I often got a syntax error or a reset of the ESP32, even with the simplest configuration.

To Reproduce Bug

Use the attached cfg and preset file.

preset_cfg.zip

Select the “Start” preset several times.

Expected Behavior

I expected that there would be no reset or error when changing the preset.
