Not really.  You’re sure you’re using the M1 executable and not the x86_64 one? I realise the version info printed by the vm doesn’t tell which one it is.  I have to fix this.

BTW if you checkout OpenSmalltalk-vm, follow building/macos64ARMv8/HowToBuild, and build in building/macos64ARMv8/squeak.cog.spur, you should be able to sign your own bundle.
