I have tested adding the provided code in my sample WebForms project and displaying the viewer in IE. Both report and the viewer were displayed successfully. Based on this test, I assume there might be some different settings of the browser on your side or some other settings of the application that prevent displaying of the report.
The issue might be connected to the Promise object failed to be loaded by the browser. When promises are not supported natively by the browser the viewer will try to load a Promise polyfill with the query https://cdn.polyfill.io/v2/polyfill.min.js?features=Promise.
The loading might fail due to some browser restrictions or connection problems. To make sure that there are no Internet connection problems and the cdn service cannot be reached for some reason, download the content of the JavaScript file (open https://cdn.polyfill.io/v2/polyfill.min.js in the browser that does not support promise natively, for example IE) and save it as a local JS file.
Then update the src attribute of the script tag to point to the local copy of the polyfill file - make sure the relative path is correct and the file physically exists in the specified folder.
For more details about required settings check HTML5 Viewer important settings.
In case the issue persists send us a sample that reproduces it in a support ticket so we can test it locally.

Katia
