Access instance property from Thread in C#

[Maddo7]

Hello,
I try to access the instance property from a thread in C# but it doesn't seem to work.

Task.Run(() =>
              {
              
                 project.SendInfoToLog("yo");
                
                // Action designer, type Set
                HtmlElement he = instance.ActiveTab.GetDocumentByAddress("0").FindElementByAttribute("body", "innertext", "body", "regexp", 0);


                // Set to attribute "innertext" value "closing tab"
                he.SetAttribute("innertext", "hello");
              });

This will only print "yo" to the console but not change the html element.
If I run the code without the Task, it works.

How can I access the instance element inside a Thread?

This means element was not found by attribute. Not the problem accessing instance property.
Where are you using this code? What element with?

I ran it as a test on the blank page that appears on ZP.
Other methoids like instance.ActiveTab.Close(); also don't work in the Task.

I tried the exact same code I posted without the Task.Run() and it worked so I assume the incorrect instance of instance is passed to the Task.

How can you test FindElement method on blank page?
Sorry, but I don't understand what you are doing.

Here is an example. The task does nothing.
