OCVWarp AppImage won't run on Raspberry Pi

The OCVWarp AppImage compiled on github's ARM64 runner will not run on Raspberry Pi 4, error screenshot below.

But OCVWarp runs when compiled on the Pi itself.

( 

In hindsight, 

This might be a problem with 
(a) /tmp not allowing executable permissions
(b) the ld-linux-aarch64.so not having executable permissions
)
