Wrong type on dynamic object with string|null

[MauroVinicius]

Describe the bug
When an object is created dynamically with string|null, Intelephense is not recognizing it as an object, in previous versions this recognition worked normally

To Reproduce

<?php

function getPokemon(): ?string
{
	return 'Pikachu';
}

$pokemon = getPokemon();
$element = 'Thunder';

$fighter = new $pokemon;
$fighter->{$element} = 'Thunder';

Expected behavior
Recognize as an object and not as string|null

Platform and version
Windows 11, Intelephense v1.10.4
