I'm making my own MOD using Geckolib, but when I start it as a test, it works fine, but when I put it in the Minecraft app, it doesn't start and crashes. crash report ---- Minecraft Crash Report ---- // Who set us up the TNT?

Ok so the game has run but when I create world, after loading terrain and joining the world,  the screen went gray and after a few minutes it kicked me out and say "Invalid player data". Could you help me?

That is correct. But that is also not the name mentioned above. You should also try using proper logging or adding a breakpoint in a debugger instead of System.out.println().

I mean, you can, it would be a different forge mod loader version. I am asking mostly because I refuse to change to 1.19.x due to Microsoft's policies and decisions about the game (the in-game chat report system)

The main task - is to make your own gui for the inventory or just a separate gui, which will implement the basic functions for the marketplace (as in the various plugins). This needs to be implemented specifically by a mod. So far I've tried creating a class that inherits the Screen and setting as new ( minecraft.setScreen(new CustomScreen())), but the main inventory stops working (not moving things from slot to slot). Also tried overriding the InventoryScreen class, but the problem is the same as above. Decided to start simple, namely adding a button to the main inventory. Logic: listening for the ScreenEvent event, and setting the new button as a widget.  @SubscribeEvent public static void openInventoryGui(ScreenEvent e) { Minecraft minecraft = Minecraft.getInstance(); if (minecraft.screen != null) { Screen current = e.getScreen(); if (current.passEvents) { Button button = new Button(10, 10, 10, 10, Component.literal("TEST"), (a) -> { System.out.println("Press"); }); e.getScreen().renderables.add(button); } } } But so far the button does not work (should output text to the console).  Regarding ScreenEvent.InitScreenEvent - I could not do anything with it (it is not in the class, found no such event). What can I read or what guides to look at this topic? Or maybe someone has advice or experience in this matter?
