### Minimal reproduction project

Ref<Animation> reset = player->get_animation(SceneStringNames::get_singleton()->RESET);
			if (reset != p_from_animation) {

					if (reset->track_get_path(i) == p_from_animation->track_get_path(p_track)) {
						
						bool used = false;
						List<StringName> animation_list;
						player->get_animation_list(&animation_list);
						for (const StringName &anim_name : animation_list) {
							Ref<Animation> anim = player->get_animation(anim_name);
							if (anim == p_from_animation || anim == reset) {
								continue;
							}
							for (int j = 0; j < anim->get_track_count(); j++) {

									used = true;
									break;
								}
							}
							if (used) {
