Mozzi on ESP32 with I2S Codec

hello, I'm runnung into problems using Mozzi with the AiThinker Auidokit. My Sketch was working fine about two weeks ago, but apparently something has changed in the ESP core and now it doesn't anymore?!

Sketch:

#include "MozziConfigValues.h"  // for named option values

#define MOZZI_AUDIO_MODE MOZZI_OUTPUT_I2S_DAC
#define MOZZI_AUDIO_CHANNELS MOZZI_STEREO
#define MOZZI_CONTROL_RATE 256 // Hz, powers of 2 are most reliable
#define ESP32_I2S_BCK_PIN 27
#define ESP32_I2S_WS_PIN 25
#define ESP32_I2S_DATA_PIN 26

// #define MOZZI_I2S_PORT     I2S_NUM_1// (default: I2S_NUM_0)

#include <Mozzi.h>
#include <Oscil.h>
#include <tables/cos2048_int8.h> // table for Oscils to play

// Synthesis part
Oscil<COS2048_NUM_CELLS, MOZZI_AUDIO_RATE> aCos1(COS2048_DATA);

void setup() {
  aCos1.setFreq(440.f);
  startMozzi();
}

void updateControl() {

}

AudioOutput updateAudio() {
  int val = aCos1.next();
  return StereoOutput::from8Bit(val,val);
}

void loop() {
  audioHook();
}

Arduino Settings:

Board: Esp32 Dev Module
Events Run On: Core 1
Flash Frequency: 40 Mhz
Flash Mode: DIO
Arduino Runs On: Core 1
Partition Scheme: Default 4MP with spiffs
PSRAM: Disabled

The ESP is stuck in a boot-loop and always spits out the follwoing errormessage via serial:

ELF file SHA256: 615c5d1ed34a1bc8

E (185) esp_core_dump_flash: Core dump flash config is corrupted! CRC=0x7bd5c66f instead of 0x0
E (194) esp_core_dump_elf: Elf write init failed!
E (198) esp_core_dump_common: Core dump write failed with error=-1

it also looks like there is a problem with the ADC...
