Hi @binZhang01
It looks like you are using a relatively old RTD version. I would recommend updating to the latest release, since it includes new features, bug fixes, and general improvements that might help resolve the issue.
Also, does this problem happen with example projects as well, or only with your project?
If possible, could you share the steps you are following? That way I can try to reproduce the issue on my side. It would also help if you can confirm the IDE version you are using.
