Hi, I have a problem with my UI Document, I create a UI Document for UI Toolkit, and I’ve added some buttons, then I’ve put a UI Document GameObject in the scene, passing the UI Document and adding a script to control the buttons, in Unity 2021 it worked fine for me, but after migrating and fixing a couple of bugs, I now find that my UI Compontent, with the buttons inside don’t work, there is not even a USS hover, nothing, I have tried many things but I have not really found any alternative but to ask this question, what tips could you give me?

I’ve been trying a few things:

1- Remove and add back the GameObject Document UI with Raycast
2-I don’t see errors in the terminal
3-EventSystem does not show Document UI events
4-When switching to simulator mode using a cell phone, the buttons work.
