If a config file does not contain a list, Minecraft crashes upon an attempt to modify the list

[KonSola5]

Using MidnightLib 1.4.1-fabric.

To reproduce:

1. Make a config with a string list.

2. Launch the game and open the config screen.

3. Try to insert something into the textbox.

4. Crash due to UnsupportedOperationException.

5. Launch Minecraft, but this time open the config screen and close it (so that the config file generates).

6. Try to insert something into the textbox.

7. Succeed.

Current workaround: Add MidnightConfig.write("modid"); below the MidnightConfig.init("modid", ConfigFile.class) so that the config file is present and filled.

This seems like an issue on your side. You need to use an array list instead of a normal one, like this: public static List<String> listTest = new ArrayList<>();

Alternatively, you can use Lists.newArrayList();
