it’s typicaly why I says “Don’t use x64 version of Raspbian”
Requirements says:
OS: Raspbian 11 // (Bullseye -- 32-bit Version) is needed
RPI 3b+ or more
Node: v16.x.x
npm: v8.x
Linux: tested and developed on Linux Debian 11
720p // HD screen or more
MagicMirror and Electron (main core) not support all features
many sub-dependencies don’t support x64 fetaures
Like i says last time, you want to use X64 version of raspbian, so assume it with a lot of bug 😉
I can’t help for this, sorry
