The shim for node:crypto in the browser is likely a weaker implementation in JS than the node implementation... you can cheat and use the browser itself to get a UUIDv4...

    function uuid4() {
      var temp_url = URL.createObjectURL(new Blob());
      var uuid = temp_url.toString();
      URL.revokeObjectURL(temp_url);
      return uuid.split(/[:\/]/g).pop().toLowerCase(); // remove prefixes
   }
