Bootloop... Could be from a number of things, from sdcard corruption to crappy (illegal) addons.
Sometimes it's better/faster to start with a clean slate.To save your data, place the sd card into a Linux machine (or Windows with some EXT4-compatibility tool) and copy the necessary folder(s).
Install a fresh copy of LE via the LibreELEC USB-SD Creator tool, and start from there. If you have no bootloop, restore your backed up files.
If the bootloop reappears, it's best to reconfigure & install everything from scratch.
Thnx for the help. I will look into to backup the data using a ext4 tool. I used the libreelec USB/SD creator. I installed the Horus build from TDB wizard i think the probleem is there.
But do you have a program that can backup ext4 =
