The WebView2 runtime might be failing to install in the background. That should be the only external dll the project might rely on.
Try downloading and running this: https://go.microsoft.com/fwlink/p/?LinkId=2124703
(If an immediate file download makes you nervous you can also go here: https://developer.microsoft.com/en-us/microsoft-edge/webview2/?form=MA13LH , and download the "Evergreen Bootstrapper" and run it.)
* If the above doesn't work then answering the following questions would be helpful.
-Are you running on windows 64-bit?
-When does this message appear? At launch?
-Can you provide a screenshot of the message?
-Does the application keep running after the message, or does it crash/close?
