Delete SME views script causing error

[TB_RIO]

I have used this script for a while in conjunction with the 'show materials for selected' in order to quickly get materials in and out of the Slate Editor. Recently (I think it corresponds with me updating to Vray 5) the clear SME views one causes the below error, and a lot of the time causes max to crash.

I'm a complete scripting luddite and don't know what this means unfortunately, can anyone help!?

Or is there a more sensible way of doing it now (I'm on 2020)

here's the script:

macroScript Delete_SME_Views
category:"Kotscript"
tooltip:"Delete SME views"
buttontext:"DeleteViews"

(
	ViewsTotal = sme.GetNumViews ()
	ViewIndex = 1
	for i in 1 to ViewsTotal do 		
	(
		view = sme.GetView (ViewIndex)
		if matchPattern view.name pattern:"*View*" then
		(
			sme.DeleteView (sme.GetViewIndex (view)) false
		)
		else
		(	
			ViewIndex += 1
		)
	)
)

Of course, it's great that you can now delete all views if you clear the scene beforehand. But the purpose of deleting all views is to clean up the scene. So it is desirable to do the whole cleaning in one automatic process.
In vain, you don't post a simple example file that can be used to reproduce failures. Knowing such "problem materials" or "scene conditions" will be useful to others.

Here is the right way to delete all sme views:

(
	if sme.GetMainframe() == undefined do sme.Open() 
	while sme.GetNumViews() do sme.DeleteView 1 false
)	

This is how to delete only "View*" named views.

(
	if sme.GetMainframe() == undefined do sme.Open() 
	for k = sme.GetNumViews() to 1 by -1 
		where matchpattern (sme.GetView k).name pattern:"View*" do sme.DeleteView k false
)
