Another error, very similar so i guess its the same bug

Exception in thread "LWJGL Application" java.lang.ArrayIndexOutOfBoundsException: 1 at com.badlogic.gdx.scenes.scene2d.ui.Table.layout(Table.java:976) at com.badlogic.gdx.scenes.scene2d.ui.Table.layout(Table.java:757) at com.badlogic.gdx.scenes.scene2d.ui.WidgetGroup.validate(WidgetGroup.java:115) at com.badlogic.gdx.scenes.scene2d.ui.Table.draw(Table.java:101) at com.badlogic.gdx.scenes.scene2d.Group.drawChildren(Group.java:110) at com.badlogic.gdx.scenes.scene2d.Group.draw(Group.java:57) at com.badlogic.gdx.scenes.scene2d.Stage.draw(Stage.java:128) at com.sketchy.game.Views.View.renderStage(View.java:83) at com.sketchy.game.Views.View.render(View.java:78) at com.sketchy.game.Views.RewindView.render(RewindView.java:96) at com.badlogic.gdx.Game.render(Game.java:46) at com.badlogic.gdx.backends.lwjgl.LwjglApplication.mainLoop(LwjglApplication.java:225) at com.badlogic.gdx.backends.lwjgl.LwjglApplication$1.run(LwjglApplication.java:126)

I think this might be caused by doing operations of libgdx classes (Scene2D) from multiple threads, like adding UI elemtents to the table while it's being rendered.

Yes. It is because of multiple threads.

I have the same exceptions and they really appear due to multithreading. I fixed some of these errors by implementing the following method in callback processing (loading resources, showing ads, etc.):

Gdx.app.postRunnable() - it's a thread save method https://github.com/libgdx/libgdx/wiki/Threading

But all the same, similar errors come to me, and it is not always possible to track where exactly they come from.

Exeption example:
