Unable to use ResourceLoader in C# after threaded load in GDScript about godot HOT 2 OPEN

This is essentially a duplicate of:

• #84407

from godot.

It looks like ClassDB can't find the method with the provided hash.

When the ResourceLoader::load_threaded_get_status method is bound, the computed hash is 4137685479. This is the same hash that C# is using to retrieve the method. However, when C# tries to retrieve this method the computed hash is 1185939122, so it doesn't match.

Why is the computed hash different? The default value for the progress argument is an empty array ([]), but when C# tries to retrieve this method, the default value was a non-empty array ([1]).

It looks like when the argument is not provided, the method modifies the default array:

In your workaround, since C# retrieves the method before it's called (and thus before the default array is modified), ClassDB is able to find the method and C# caches it.

Another way to workaround this would be to provide a value for the progress argument:
