LVGL Lottie plays partially then crashes

[tank104]

Describe the issue Using LVGL Lottie with ESP32-S3 Touch LCD 1.28 plays about 1/4 of lottie and then crashes out without any guru meditation error.

Code to reproduce the issue

static void show_lottie(void) { / Task lock / lvgl_port_lock(0);

extern const uint8_t lv_example_lottie_approve[]; extern const size_t lv_example_lottie_approve_size;

lv_obj_t *lottie = lv_lottie_create(lv_screen_active()); lv_lottie_set_src_data(lottie, lv_example_lottie_approve, lv_example_lottie_approve_size);

static uint8_t buf[64 64 4]; lv_lottie_set_buffer(lottie, 64, 64, buf);

lv_obj_center(lottie);

/* Task unlock */
lvgl_port_unlock();

}

void app_main(void) { ESP_ERROR_CHECK(app_lcd_init()); ESP_ERROR_CHECK(app_lvgl_init());

show_lottie(); }

Expected Results

Lottie animation to play in full.

Actual Results

Lottie animation plays around 1/3 and then crashes with below error

Is it strange I don't get a Guru Meditation error? Really stumped how to debug that error since so little information is given, but I certainly am not an expert on ESP-IDF yet.

Also other LVGL examples work fine - like lv_example_chart_1()

Just not lv_example_lottie_1() (which the code above is a copy of)

[tank104]

Does anyone know anything I could do to help investigate or debug this?
