same here it crash my game when usiing fabric

I believe this is the crash I've just encountered, so I've look at the compiled code and followed the stacktrace backwards.

Exception: a NullPointerException (AbstractButtonWidget.message.getString() throws an NPE)

Cause: In GuiConfigWaila, the buttons are created with a Text parameter being null. During the AbstractButtonWidget.<init>, the parameter is saved to message. Now when HWYLA creates the OptionsEntryButton, it calls setMessage with a non-null Text object. At this point, the setMessage compares the Text.getString() method for each of them and checks their equality. This is where the crash happens.

Code snippets:

AbstractButtonWidget:

    public void setMessage(Text text) {
        if (!Objects.equals(text.getString(), this.message.getString())) {
           this.queueNarration(250);
        }

        this.message = text;
    }

GuiConfigWaila:

options.add(new OptionsEntryButton(Util.createTranslationKey("config", new Identifier(Waila.MODID, "general")), new ButtonWidget(0, 0, 100, 20, /* NPE-causing value */ null, w -> { /* ... */ })))
// and a couple more

OptionsEntryButton:

    public OptionsEntryButton(String title, ButtonWidget button) {
        this.title = I18n.translate(title);
        this.button = button;
        // This call is the method that throws an NPE, due to the above code.
        button.setMessage(new LiteralText(this.title));
    }

Solution: Set the default button texts in GuiConfigWaila from null to a non-null value (ex. new LiteralText("")). This will result in the AbstractButtonWidget.setMessage(Text) call to not NPE because neither read value will be null.
