Very strange. I just upgraded my system to RPi 4B with LE12 and downloaded squeezelite from https://sourceforge.net/projects/lmscl…tar.gz/download
I have made squeezelite executable (744) and when I try to run it here is what I get.
LE12 can not find squeezelite while it is right there.
The same process works on RPi 3B+ with LE 9.2.8.
