Updating Kendo on ASP.NET MVC 5 Stackoverflow exeption

Question

I'm getting a Stackoverflow exeption after updating my ASP.NET MVC Project to the latest Version of Kendo UI. Tested with R3 2020 and R2 2020, the previous Version which worked was R2 2018. I have checked the .NET and ASP.NET Version on the Server.

Error Log Failure on the Server:

I faced the same type of error. It took me quite a while to find the issue: The problem in my case was, that I had a dynamic variable where I called the .ToString() function inside my kendo grid column ClientTemplate:

.ClientTemplate("Some html string" + ViewBag.SomeObject.ID.ToString() + "End of html string")

I solved the problem by creating a variable of type int and forced the type onto the variable:

@{
    var id = (int)ViewBag.SomeObject.ID;
}

and then I changed my ClientTemplate to:

.ClientTemplate("Some html string" + id.ToString() + "End of html string")
