If you use the Cuis-Smalltalk-Devv/clonePackageRepos.sh script you will 
have this, along with other helpful packages.

Yes.  This is a known problem (Issue #574)

On arm64, use of Stack VM is noted in the documentation
   
https://github.com/Cuis-Smalltalk/Cuis-Smalltalk-Dev/wiki/VectorGraphcis-plugin

This appears to be a problem with cache flush or stack usage, so 
segfault appears random and with stack pointer bad it is painful to 
debug.

The Aarch64/Arm64 Cog is under heavy development right now.  It should 
come back better, but right now patience is required.

If you are highly skilled (think gdb), you could help out here, but it 
is beyond my personal skill set.
