Can you please double check if the installed extension in Chrome is Progress Telerik Test Studio
2018.3.103? Also, if there are any other Test Studio related extensions, please remove them completely as they can be preventing the normal flow of our product.
If the above is not working, or you have the Telerik Test Studio 2018.3.103 extension solely installed on your side, please follow the next steps in attempt of resolution to the issue you are experiencing:
1. Uninstall Chrome completely from your machine
2. Then, navigate to C:\Users\<YousUsername>\AppData\Local\Google\Chrome and delete any leftover data in this folder
3. Next, perform a fresh install of the Chrome browser again.
4. Finally, try to execute a test which handles a Confirm dialog and see if it will succeed this time.
Last, if the steps do not help as well, is it possible for you to share the failure exception text for further reference?
Thank you in advance for your cooperation.
