Hello Chan,
We will need more information for sure. Instead of starting the recorder from the regular place when the test is opened, can you please start it from the Help - Record option? This will open another dialog with the recorder log. Please add the log into a .txt file and submit a formal support ticket where you can send it to us as attachment.
If also possible please share a public url of the application if any and grant us access if needed. You can also use the support ticket for any private info you don't want to share publicly. Observing the exact problem and be able to debug it will help us work on resolving the issue.
Thanks a lot for your cooperation and understanding!
Kind regards,
Konstantin Petkov
the Telerik team
