Expectation:

When pressing the “Edit” button, the world edit screen should open properly, allow you to navigate to the screen containing behavior/resource packs, and should show an error message under the pack which has any issues without crashing the game.

Issue:

When clicking on the button labeled “Edit” under any installed world, irrespective of the packs directly applied to that world, the game will immediately crash. This issue occurs if there is a behavior/resource pack present in the development_behavior_packs or development_resource_packs folders (may extend to the behavior_packs and resource_packs folders as well) that have a missing dependency. The issue can be resolved by removing any packs which have missing dependencies or resolving the dependency issue by changing pack UUIDs.

Reproduction Steps:

1. Download the attached zip file containing a simple BP/RP combination, where the resource pack is misconfigured with the wrong dependency UUID.

2. Place crash_enabler_BP into the development_behavior_packs folder.

3. Place crash_enabler_RP into the development_resource_packs folder.

4. Launch the game.

5. Find any world and click on the “Edit” button below it.
