Could you install package "file" (pkg install file) and then post output of file /data/data/com.termux/files/usr/bin/zsh ?

zsh works on my device (ARM, android 5.1) without any problem.

Interesting how AArch64 binary was installed on your device.

Try to reinstall it with pkg reinstall zsh. If this won't solve problem, post apt logs (at least urls) here.

Thanks. Reinstalling fixed the problem.
