Wii u keep crashing | need help please

Hi everyone, since ~ january my console cant launch any game or any app (like the settings).

I can navigate in the menu but when i click on any thing, i'm getting blocked in the charging screen and i sometimes still get the sound of the charging screen and sometimes no

Some informations that may help you to help me : i dont get any USB thing plugged in it, im not connected to internet or any networ, i didn't modded it so i got official games and official OS and i also dont get any error code just a static screen

if anyone can help me i would be very grateful bc i got my console since my childhood and replacing it would be terrible for me

Thanks in advance !
