It looks like the old client ignores some fields of new service response. You have already checked the mapping. So the only reason I can see is datamember order - the datacontractserializer depends on it. Try as follows:
Edit your sample service datacontract:
Add DataMember-Attribute if not already present.
Set DataMember(Order = 1) on members of original version.
Set DataMember(Order = 2) on members of new version.

If you already specified DataMember-Order - do not update order of original members; instead make sure new members have a higher order than highest original member order.

I hope this will solve your issue - good luck.
PS: Soap service versioning is a common scenario, the are many articles on web.

Another idea:
Diff generated service client code before vs after update. Pay attention on member names, namespaces and order.

Why don't use "view.Table" or "view.Cast<DataRowView>().Select(drv => drv.Row).ToArray()" for update?

Do you ever remove the old control before adding a new one to panel1.Controls?

Creating ScreenDrawing transparent (CreateParam: WS_EX_TRANSPARENT) harms internal visibility-order logic. You can fix it calling:
foreach (var drawControl in Controls.OfType<DrawControl>()) drawControl.Invalidate();
or similar in Form.Resize or:

1.) Use an image specific region (Control.Region property) instead of transparency. See https://www.codeproject.com/articles/6048/creating-bitmap-regions-for-forms-and-buttons

or 2.)
Handle paint event of your PictureBox to draw the sprites. This approach will require some additional code to invalidate drawing area when moving sprites.

I assume Form1.GameWindow is a DrawControl instance. You are updating its size in Form1.Resize and in DrawControl.Paint with different values. You should never update control properties in Paint-event.
Have a look at Form.SetStyle, ControlStyles.AllPaintingInWmPaint and Form.OnPaintBackground documentation. It looks like you want to paint the image as background.

Try this:
- copy the form containing your tab control
- rename copied files and class name (in .cs and .desinger.cs)
- open copy in designer and remove all unwanted control and components
- save file
- unload project
- change baseclass of copied form to UserControl
- reload project
- there may be some code-issues in .cs and designer.cs because of changed baseclass; repair them
Good luck!

Open a second VS instance, attach debugger to first instance, enable exceptions "break when thrown" in second instance. Now try to open form-designer in first instance. I hope this will give you a clue - good luck.

WeakReference.Target will be null when the GarbageCollector has collected the Form. Form.Close() does not call GC.Collect() - and you should not do it in your code (see GarbageCollector documentation). You should probably perform another check on Form.IsDisposed.

Copy...()-method will be called when you start the service at 11:40 AM (hour == 11 && minute == 40). Create_ServiceStoptextfile always when the service stops.

Tells the 'unspecified' exception you there is no ACE.OLEDB-Provider installed? If yes, the issue is probably that there is not 64-bit provider installed.

This means your code is executed within the static constructor or initialization of static fields and your code fails.
I) Typeinitializer should never cause exceptions.
II) See InnerException for the reason.
