Unity keeps crashing and I dont know why

So I’m fairly new to using Unity so I don’t know everything about it. The problem is that Unity keeps crashing for no reason and I wanted to ask if some of u can get behind my promblem.
This is the part of my Code thats causing the Problem (I think…) Its very long and probably really bad but like I said I can’t really pinpoint the reason unity keeps crashing. (The Code is for an Enemy in a Turn Based Combat (kinda like DnD) and it normally keeps chrashing on the Turn right brfore the Enemy gets close enough to the player to Attack)

void Update()
{
if (Leben <= 0)
Die();

    if (Turn == true)
    {
        if (CheckPlayerProx() == 1)
            closeProx= true;
        else
            closeProx= false;

        if CheckClose() == 1)
            close= true;
        else
            close= false;

    }
}

void CheckMove()
{
    rechts = 0;
    links = 0;
    oben = 0;
    unten = 0;

    while (Movement > 0 && closeVal== false)
    {
        if (XGegen - 1 > XWert)
        {
            Movement--;
            XWert++;
            rechts++;
        }

        if (XGegen + 1 < XWert)
        {
            Movement--;
            XWert--;
            links++;
        }

        if (YGegen - 1 > YWert)
        {
            Movement--;
            YWert++;
            oben++;
        }

        if (YGegen + 1 < YWert)
        {
            Movement--;
            YWert--;
            unten++;
        }

        if (XWert == XGegen + 1 && YWert == YGegen - 1)
        {
            int ur = Mathf.RoundToInt(Random.Range(1f, 2f));
            if (ur == 1)
            {
                Movement--;
                YWert++;
                oben++;
            }
            else
            {
                Movement--;
                XWert--;
                links++;
            }
        }
        else
        {
            if (XWert == XGegen - 1 && YWert == YGegen - 1)
            {
                int ul = Mathf.RoundToInt(Random.Range(1f, 2f));
                if (ul == 1)

I suspect that the while loop inside your Update method causes an infinite loop, which then crashes Unity. Check your conditions, e.g. print out the variables used in the condition statement.
