### Issue description

E 0:00:47:0705   Message.gd:46 @ from_raw(): Class 'FileAccess' or its base class cannot be instantiated.
  <Erreur C++>   Condition "!ti->creation_func" is true. Returning: nullptr
  <Source C++>   core/object/class_db.cpp:341 @ instantiate()

`from_raw() is a byte_to_var_with_objects() function`

### Steps to reproduce

try to decode an array containing a FileAccess object among many other vars

byte_to_var_with_objects([FileAccess.open(path, FileAccess.READ), a, b, c, d, ...])

### Minimal reproduction project
