Restore your registry from the back up or restore point.

This is what you want because it will identify the exact location of the problem, and allow you to identify the object causing it. If you are working with unsafe code and you get a NullReferenceException, https://rocketdrivers.com/errors-directory/15133 just be aware that the offending pointer need not be null. It can be any location in the lowest page, and this exception will be produced. Well, suppose we have a struct containing two ints, and an unmanaged pointer equal to null. If we attempt to dereference the second int in the struct, the CLR will not attempt to access the storage at location zero; it will access the storage at location four. But logically this is a null dereference because we are getting to that address via the null. Dereferencing any invalid pointer that falls in the lowest page of virtual memory causes the same operating system error, and thereby the same exception.
Any controls which are in a container control will not be found in Me.Controls; they will be in the Controls collection of that Panel or GroupBox. Nor will a control be returned when the control name is misspelled (“TeStBox2”). In such cases, Nothing will again be stored in those array elements and an NRE will result when you attempt to reference it. Among other things, this code does not anticipate that the user may not have selected something in one or more UI controls. ListBox1.SelectedItem may well be Nothing, so ListBox1.SelectedItem.ToString will result in an NRE. The problem is that Dim does not create a CashRegister object; it only declares a variable named reg of that Type.
