Error at importing Autopilot with M1 Mac

[greenmoonslug]

file:

//autopilot1.dn.js
import * as autopilot from "https://deno.land/x/autopilot@0.4.0/mod.ts";

when I run this:

% deno --unstable run --allow-ffi --allow-env --allow-read autopilot1.dn.js

error: Uncaught (in promise) TypeError: Error parsing args at position 0: data did not match any variant of untagged enum ForeignSymbol
  return Deno.dlopen(file.path, symbols);

• Device: Mac mini (M1, 2020)
• OS: MacOS Monterey 12.5
• Deno 12.4.3
• Autopilot 0.4.0

Note

According to README.md, the command should be:

% deno run --unstable --allow-ffi autopilot1.dn.js

Though, Deno.dlopen isn't defined when I put --unstable after run.
When I just put --unstable before run, that requests:

• env access to "DENO_DIR"
• env access to "HOME"
• read access to "~/Library/Caches/deno/plug/https/github.com/c7ce6d2dafee0de7e635a6112ad5903d788bace477d867b0a342e540acf23633.dylib"
• read access to "~/Library/Caches/deno/plug/https/github.com"

And when I arrow all of these, same error causes as with --allow-env --allow-read.
