Cannot open Combat Tracker config on v12

[BoltsJ]

Attempting to open the Combat tracker configuration on v12 throws an error and fails to open the window.

To reproduce:

1. Launch a world on v12
2. Click the cog icon in the combat tracker
3. The config window doesn't open and the following error is printed to the console:

This happens even with no modules enabled.

Same for me on Simple Worldbuilding with Foundry v.12 build 328, no dialog opens and I receive the kind of error below. Note that the same error arises even without the lib-wrapper module or with no module installed. Cannot read properties of undefined (reading 'Actor'). Same kind of error when I try to open Configure Default Token Settings

Error: An error occurred while rendering CombatTrackerConfig 27. Cannot read properties of undefined (reading 'Actor')

The same happens for me. No modules activated.
