I kept on getting error that says "Error in port widths or dimensions. 'Output Port 1' of 'simulink_​controller​/Sum2' is a [2x2] matrix."

How can I solve the mentioned error? I couldn't figure out as I am new to simulink.
Thank you.

This is my simulink model. I have code written in matlab for lqr controller with non zero set point. I have 2 states x1 and x2 but my output of interest is x2 only. I get two errors :
Error in port widths or dimensions. 'Output Port 1' of 'simulink_PNZSP_controller/Sum2' is a [2x2] matrix.
Component:Simulink | Category:Model error
Error in port widths or dimensions. Invalid dimension has been specified for 'Input Port 1' of 'simulink_PNZSP_controller/integrator'.

Pass the output of the Sum2 block through a Selector block https://www.mathworks.com/help/simulink/slref/selector.html

I tried using that block still, it shows the same error since the error is shown in the output port of sum block before output reaches the selector block.
