I'm not familiar with Kendo but I'm guessing this is a ASP.NET MVC website and Kendo is using the builtin bundle optimisation from that. A lot of problems that arise with this optimiser either has to do with incorrect file paths, the order of inclusion and/or excluded files based on their filename.
Check the network console if there are any 404 to detect incorrect path requests.
You can enforce the correct ordering like this.
If the (debug) Kendo javascript files are indeed not arrayified correctly, dependency injection will fail. I'm guessing Kendo already comes with a pre-minified version called something like kendo-blabla.min.js. The bundle optimiser should, by filename convention, include this file instead of minifying the debug version himself but I've some projects where this failed. The easiest way around this is including the pre-minified instead of the debug version in the bundle directly:
var kendoJs = BundleTable.EnableOptimizations ? "~/path-to/kendo.js" : "~/path-to/kendo.min.js";
