My WPF application does not start on another PC, while an application with no MySql works, what could be the problem?

This is my first using a database. I’ve made an application that contains tables in dbForge through mySql localhost with XAMPP. I copied all my files and downloaded the latest 6.0 framework on the other PC, but it does not start, and it is not giving any error messages. Furthermore, I can see in the Task Manager that it opens for some seconds and then closes.

Also, I tried it with a different application without mySql and that application started. What common mistakes could I have? I can provide more information, if needed, but right now I can’t tell what should I be even checking.

The connection code block:

public class ApplicationDbContext : DbContext
{
    public DbSet<Berletes> Berletesek { get; set; }
   
    protected override void OnConfiguring(DbContextOptionsBuilder optionsBuilder)
    {
        var connetionString = "Server=localhost; Database=foxgymapp; Uid=root; Pwd=;";
        optionsBuilder.UseMySql(connetionString, ServerVersion.AutoDetect(connetionString));
    }

    protected override void OnModelCreating(ModelBuilder modelBuilder)
    {
    }
}
