Unhandled TypeLoadException caused by the generic type 'ByRefFunc`2'

Question

I was working on a web app project using asp net core 5.0 and razor pages and it was going smoothly until it started giving me this error when i wanted to redirect to another page:

An unhandled exception occurred while processing the request.

From what i can see it's an instantiation problem in the Microsoft.AspNetCore.Mvc.Core dll but i don't know what to do can somebody help me?

The redirect code on the Index.cshtml.cs:

public ActionResult OnPostRedirect(string ipAdd)
        {
            //deviceIp = ipAdd;
            return Redirect($"/InterfaceTraffic/{ipAdd}");
        }

The top part of the page InterfaceTraffic.cshtml:

@page "/InterfaceTraffic/{ip}"
@model WebSniffer.Pages.InterfaceTrafficModel
@{
    ViewData["Title"] = "Selected Interfaces Traffic";
}

And the on get function in InterfaceTraffic.cshtml.cs:

public void OnGet()
        {
            capture = false;            
            device = CaptureDeviceList.Instance.FirstOrDefault(x => parseDevice(x)[1] == ip);
            if (device == null)
                Redirect("/");
            devicePorp = parseDevice(device);
            device.OnPacketArrival +=
                new PacketArrivalEventHandler(OnPacketArrival);            
        }
