Editing any chararcter/skin for the second time softlocks the game

When you open the "edit chararcter/classic skin" screen for the second time you will be sent into an empty screen with a loading animation in the top right corner where the back button becomes unusable, causing the game to get softlocked.

Step to reproduce:

1. Go to Dressing Room -> Edit Character/Classic Skin
2. Go back to Dressing Room
3. Press Edit Character/Classic Skin again

Expected result:
The screen properly loads and the game isn't softlocked.

Observed result:
The game is softlocked.
