Guru Meditation Error on passing the user_data to 'add_event_cb',

[sam0910]

Describe the bug
btn.add_event_cb(event_cb, lv.EVENT.ALL, None) is okay, but
when passing user_data, error occurs.

If you are having a problem compiling paste the build output below. (NO SCREENSHOTS)

LVGL MicroPython 
IDF version : v5.4
Machine     : Generic ESP32 module with SPIRAM with ESP32

Guru Meditation Error: Core  1 panic'ed (LoadProhibited). Exception was unhandled.

If your problem is running the binding please past the code you are using below.*
I need to see ALL of the setup code exactly as it is being ran.

import lvgl as lv
import display

def event_cb(e):
    code = e.get_code()
    label = e.get_user_data()


scr = lv.screen_active()
btn = lv.button(scr)
btn.set_size(100, 50)
btn.center()

info_label = lv.label(scr)
info_label.set_text("None")

btn.add_event_cb(event_cb, lv.EVENT.ALL, info_label)
# btn.add_event_cb(event_cb, lv.EVENT.ALL, None) is okay

import task_handler
task_handler.TaskHandler()

**Exact make and model number of the MCU that you are compiling for or the firmware is running on. **

• Make: Lilygo
• Model: ESP32

For ESP32 MCU's The PSRAM and FLASH SPI type, quad SPI or octal SPI.

• PSRAM: quad
• FLASH: quad

I need to know the OS and OS version of the machine that compiled the binary. If using a VM then I need to know the OS and OS version the VM is running. (WSL == VM)

• OS: macos

it should have generated a back trace when the core panicked. I need you to decode that backtrace and paste the decoded output to me so I can see exactly where it is failing.

[sam0910]

I've decode it with command
xtensa-esp32-elf-addr2line -pfC -e ./micropython.elf 0x4008505c:0x3ffd8160 0x401ad189:0x3ffd8190 ...

Backtrace

Backtrace: 0x4008505c:0x3ffd8160 0x401ad189:0x3ffd8190 0x400d6d26:0x3ffd81b0 0x400df839:0x3ffd8200 0x400d5929:0x3ffd8260 0x401b37c1:0x3ffd82a0 0x401b3883:0x3ffd82c0 0x4008677a:0x3ffd82e0 0x401adc5c:0x3ffd8380 0x401b37c1:0x3ffd83f0 0x400866d9:0x3ffd8410 0x401adc5c:0x3ffd84b0 0x401b37c1:0x3ffd8510 0x401b37d6:0x3ffd8530 0x401e082e:0x3ffd8550 0x401e0a36:0x3ffd85e0 0x401c4366:0x3ffd8630

ok so after looking at the code it appears that the user data is reserved for internal purposes.
