Hello @Cenk,
Please kindly try following:
Close the web browser, sign out Visual Studio, sign in VS again, launch VS > Help > Send Feedback > Report a Problem…
If you still fail to report the feedback, you can consider using .NET entry as a workaround currently. After you submit the ticket, try to edit the tag(on Developer Community), add Visual Studio related tags.
Sincerely,
Tianyu
