Not all diagrams are supported out-of-the-box by all previews, and some like blockdiag require to install the specific converter and have it in the system path*.
In this case, I tested vscode and intellij and it only worked in the latest once I install blockdiag :/

If you can render the pdf from shell, that means you have the commands installed, so my suggestion is to ask in the respectives repositories of the previewers to support it.


* There are third party options like kroki that rely on webservices, but I don't know if some previewer uses it.
