Win32 Exception: 0xc0000005 | dll injection

So today I tried dll injection to game (assult cube) to test my experience with my job.
But I got problems with Win32 Exception: 0xc0000005.
My code looks like:
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading;
using System.Threading.Tasks;
using System.Windows.Forms;
using Memory;
namespace AssultCube_Cheat
{
public partial class Form1 : Form
{
Mem assultcube = new Mem();
public static string RifleAmmo = "ac_client.exe+0x0017E0A8";
public Form1()
{
InitializeComponent();
}
private void Form1_Load(object sender, EventArgs e)
{
int PID = assultcube.GetProcIdFromName("ac_client");
if (PID > 0)
{
assultcube.OpenProcess(PID);
Thread WA = new Thread(writeAmmo) { IsBackground = true };
WA.Start();
}
}
private void writeAmmo()
{
while (true)
{
if (checkBox1.Checked)
{
assultcube.WriteMemory(RifleAmmo, "int", "80");
Thread.Sleep(2);
}
Thread.Sleep(2);
}
}
}
}
I tried updating my computer drivers, upgrading my system to Windows 11 but problem didnt fix.

Below is my code that is displaying only the Title and Description:

}
private void button1_Click(object sender, EventArgs e)

try
{
XmlReader FD_readxml = XmlReader.Create(textBox1.Text);
SyndicationFeed FD_feed = SyndicationFeed.Load(FD_readxml);
TabPage FD_tab = new TabPage(FD_feed.Title.Text);
tabControl1.TabPages.Add(FD_tab);
ListBox FD_list = new ListBox();
FD_tab.Controls.Add(FD_list);
FD_list.Dock = DockStyle.Fill;
FD_list.HorizontalScrollbar = true;
foreach(SyndicationItem FD_item in FD_feed.Items)
{
FD_list.Items.Add(FD_item.Title.Text);

FD_list.Items.Add("---------");

Autoplay video on windows form

i am new to .net i am having trouble playing videos automatically. I would be showing different textboxes here but i want the video to autplay without any buttons
using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Windows.Forms;
using WMPLib;
namespace ThinkQDisplay
{
public partial class Form1 : Form
{
public Form1()
{
InitializeComponent();
}
private void axWindowsMediaPlayer1_Enter(object sender, EventArgs e)
{
AxWindowsMediaPlayer1.URL = "C:\Users\Ramrod\Documents\Visual Studio 2012\Projects\ThinkQDisplay\ThinkQDisplay\sample.avi";
}
}
}
It keeps telling it is an unrecognized escape sequence. Also I would like to have a separate form (form2). Where I can choose what to play here on form 1. Is it also possible to have it looped?

private void axWindowsMediaPlayer1_Enter(object sender, EventArgs e)
{
axWindowsMediaPlayer1.URL = #"C:\Users\Ramrod\Documents\Visual Studio 2012\Projects\ThinkQDisplay\ThinkQDisplay\sampler.avi";
}
private void Form1_Load(object sender, EventArgs e)
{
axWindowsMediaPlayer1.settings.autoStart = true;
}
}
}

How to open a file an display it in a TextBlock c#

So im pretty much just starting out with c# and i'm just trying to get the text out of a .txt file and display it on my App. I've tried looking everywhere that I can think of but i've only found people doing this for console Apps and when I try apply the same solution to mine it will just gives errors. This is what i'm trying to use at the moment but I just keep getting the error: "cannot convert 'string' to 'System.IO.Stream'" for the path after StreamReader(path). Ive tried it as an console app(changing the output code) and works fine
namespace FileOpenApp
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
private void inputSubmitButton_Click(object sender, RoutedEventArgs e)
{
outputBox.Text = "Testing";
processFile();
}
private void processFile()
{
try
{
string path = #"C:\Users\Fabian\Dropbox\test.txt";
using (StreamReader sr = new StreamReader(path)) //errors here
{
string line;
while ((line = sr.ReadLine()) != null)
{
outputBox.Text = line;
currentProcess.Text = "Done";
}
}
}
catch (Exception e)
{
currentProcess.Text = "Something went wrong";
}
}
}
}
Edit: trying to use this code I am getting the error that File does not exist in the namespace System.IO
using System;
using System.Collections.Generic;
using System.IO;
using System.Linq;
using System.Runtime.InteropServices.WindowsRuntime;
using System.Text;
using Windows.Foundation;
using Windows.Foundation.Collections;
using Windows.UI.Xaml;
using Windows.UI.Xaml.Controls;
using Windows.UI.Xaml.Controls.Primitives;
using Windows.UI.Xaml.Data;
using Windows.UI.Xaml.Input;
using Windows.UI.Xaml.Media;
using Windows.UI.Xaml.Navigation;
namespace FileOpenApp
{
public sealed partial class MainPage : Page
{
public MainPage()
{
this.InitializeComponent();
}
private void inputSubmitButton_Click(object sender, RoutedEventArgs e)
{
outputBox.Text = "Testing";
processFile();
}
private void processFile()
{
string path = #"C:\Users\Fabian\Dropbox\test.txt";
string contents = "";
System.IO.File.ReadAllText(path, contents);
outputBox.Text = contents;
}
}
}
Also tried;
string path = #"C:\Users\Fabian\Dropbox\test.txt";
outputBox.Text = File.ReadAllText(path);

You should call File.ReadAllText(), which does all of this for you and returns a string.
