The custom code works in intelliJ but gives an error in Mcreator

My custom code works perfectly in intelliJ, but when I put the same code in Mcreator, it gives this error:

 

Failure message: api_test (api_test) encountered an error during the construct event phase
java.lang.NullPointerException: Cannot invoke "net.minecraft.client.gui.Font.width(net.minecraft.network.chat.FormattedText)" because "net.minecraft.client.Minecraft.getInstance().font" is null

Exception message: java.lang.NullPointerException: Cannot invoke "net.minecraft.client.gui.Font.width(net.minecraft.network.chat.FormattedText)" because "net.minecraft.client.Minecraft.getInstance().font" is null

Code:
ConfigCategory general = builder.getOrCreateCategory(Component.literal("general")); 
        ConfigCategory preview = builder.getOrCreateCategory(Component.literal("preview")); 
        builder.setTitle(Component.literal("My Mod Config")); 
        builder.setDefaultBackgroundTexture(new ResourceLocation("minecraft:textures/block/stone.png")); 

        general.addEntry(entryBuilder.startIntField(Component.literal("Field int"), 10).setDefaultValue(10).setMin(0).setMax(100).build();

What is the problem with code?
