Mods Disable After Opening Mod Settings

When creating a world, if I open the settings of an editable mod/add-on and cancel or exit, all enabled resource packs and behavior packs are automatically disabled.

Steps to Reproduce

1. Create a new world.

2. Enable any editable mod/add-on.

3. Open the mod’s settings and cancel/close it.

4. Check the world packs again.

All previously enabled packs are turned off automatically.
