    I added the runtime shader in the UIToolkit/Shaders directory to the Graphic shader list to solve this problem

    Hello,

    When you upgraded did you keep using PanelRenderer or did you upgrade your scene to use UIDocument and Panel Settings?

    Where did you find this shader? I am getting the same exception in a windows build and with a different callstack, but it's worth a try.
