ESP guru meditation error (LoadProhibited) with Blynk

[Jfox99]

Hardware: Board: DOIT ESP32 DEVKIT V1 Core Installation version: 1.0.4 IDE name: Arduino IDE Flash Frequency: 80Mhz Upload Speed: 115200 Computer OS: Windows 10 PRO

Description: Hi guys I'm using blynk with the menu interface tool to select various patterns for my ws2812b led strip. The problem is that with one particular pattern, the music reactive pattern, the ESP crashes, reporting then the guru meditation error (LoadProhibited). With the other patterns I don't have any issue. Flashing only the music reactive void the code runs great without problems. I've tried to increase stack in the main.cpp but same results
