Error in port widths or dimensions. 'Input Port 3' of 'Project/model11/Multiport Switch1' is a one dimensional vector with 1 elements.

I'm getting this error, the model looks good, but when the output from From10 goes to Multiport switch1, it's showing port errors, why? how to resolve such error?

The error message is clear. The From block is feeding 4 numbers. Is that what you expected? Show or attach your model to get help.
