Aby idea why libreelec can't start ?
Last working version is #0429

Yes because you're using Berryboot, which isn't supported by LibrELEC.

Berryboot butcher the LibreELEC supplied images (including mine) by ripping out the kernel, RPi firmware, kernel modules and associated firmwares that we have spent time creating and testing, then expect LibreELEC to boot with a completely alien kernel, often out of date RPi firmware, and missing most kernel modules and firmwares. They continue to call the resulting image a LibreELEC image, lulling users into believing they're getting the real deal when they're getting no such thing. The resulting image is not anything we recognise, and certainly nothing we are able to support.

Contact Berryboot for your support, or better still, stop using Berryboot and install LibreELEC directly to the SD card.

Edit: Ah, @HiassofT beat me to it.
