I have the same problem. I will try to add more information about it. The file is loaded w/o errors After clicking on view job there is an error: "An error occurred when processing your file viewer may not work. Please try another file." After clicking on OK, the second error appears: "Object reference not set to an instance of an object." After OK, the viewer starts but is empty. I tried with other files. The same result. The operating system is Windows 10 Version 10.0.19042 Build 19042.
