❔ System.NullReferenceException 'Object reference not set to an instance of an object.'

Hello!
I'm getting a little desperate here:
This is my index code:
public IActionResult Index()
        {
            // List<Tipo> list = _context.Tipos.ToList();
            List<string> list = new List<string>();
            list.Add("Home");
            list.Add("Home");
            list.Add("Home");
            list.Add("Home");
            return View(list);
        }

This is my index.cshtml:
<select class="form-select" name="tipo" id="tipo">
            @foreach (var item in Model)
            {
                <option value="abc">abc</option>
            }
        </select>

Why do I get this exception? I've been at it for over an hour, I'm new at this, and I'm very confused

where is the exception occuring

At the Foreach, the "Model" part
DDeluxe12/16/2022
is this happening when the page first loads, or after you try to submit a form or something? As is, it seems fine

When I try to run the app

._.' Closed the project, re-opened and my HomeController had gone to its initial state
Tried doing the exact same thing, it's now working, for some reason :|

Was this issue resolved? If so, run /close - otherwise I will mark this as stale and this post will be archived until there is new activity.
