Problem

I think because of this line, but I don't know the reason why need to use system cache, because there's no useful document to point out intention.

Temporary Solution

Currently, I fork plug and add the following code to skip the cache, this will solve the issue temporarily.

  ...

  if (options.policy === CachePolicy.NONE) {
    return new URL(url).pathname;
  }

  const file = await plug.cache(url, policy);

  return file.path;
}

I'm facing this problem too. When cache policy is NONE, x/cache will always copy ./target/debug/*.lib to cache directory. So the lib in cache will always have a new but Deno.dlpopen didn't work.
