WARN ConfigProvider: failed to load overlay config (java.lang.NullPointerException: null)

[Heitzenberg]

When trying to open a world in MCA Selector 2.6.1, it freezes and crashes with the following log:

20:46:26.700 [main] WARN ConfigProvider: failed to load overlay config
java.lang.NullPointerException: null

I tried deleting the config file(s) and reinstalling, which did not fix the issue.

Environment:

• OS: Windows 11
• Java version: 21.0.9
• Version of MCA Selector: 2.6.1
