ProjectSettings.load_resource_pack hangs up UI on Android

[MinatoTW]

Tested versions

• Reproducible in all versions after 4.4.beta1

System information

Windows 10 - Godot 4.5.dev1

Issue description

We load a pck file on startup, which hangs up the UI on Android. It works fine on Windows & Linux. This happens on all versions after 4.4.beta1, I've checked all of them to no avail.

The attached project shows how the animation stops while the pck is loading. I'm adding a video as well.

Steps to reproduce

• Create a pck file with the same version of Godot.
• Use ProjectSettings.load_resource_pack to load it
