The extension has started locking up itself and other vscode extensions for me when previewing a .dot file it previously was able to render ~10 months ago. I can't help but wonder if this is a vscode issue. Perhaps it's stricter now in killing extensions that are CPU-hungry.

• Extension Version: v0.3.5
• OS Version: Windows_NT x64 10.0.19044
• VS Code version: 1.75.1

After some testing of various graphs I have lying around:

• 9 nodes and 18 edges works
• 73 nodes and 90 edges works
• 74 nodes and 102 edges works
• 64 nodes and 65 edges fails. File: outer-wilds-no-dlc.dot
• 100 nodes and 102 edges fails. File: outer-wilds.dot (this file specifically used to work ~10 months ago)

I see this frequently:

The extension 'Graphviz Interactive Preview' took a very long time to complete its last operation and it has prevented other extensions from running.

And sometimes this:

Error loading webview: Error: Could not register service workers: InvalidStateError: Failed to register a ServiceWorker: The document is in an invalid state..

Finally, here's the profiling information that vscode really wants me to attach: tintinweb.graphviz-interactive-preview-unresponsive.cpuprofile.txt

I've only started using the extension today and it locks up so frequently (Rendering Graphviz view) when I preview an autogenerated dot file that I have to close and reopen vscode to be able to run other build tasks or see Github status. I can't really use the extension like this.

The hangs tend to happen more when the preview window is open, so it looks like a recurrence of (or has the same core issue as) #138.

And maybe 50% of the time when I reopen vscode, the extension fails to show any preview, with the The document is in an invalid state.. error mentioned above, and I have to close and reopen again to try it.

Extension version: 0.3.5
VSCode Version: 1.75.1
OS: Linux x64 6.1.7-200.fc37.x86_64

Just leaving my two cents that I am experiencing the same issues described by @Zannick from two weeks ago. Seems like a great extension aside from this issue. I get the problem whenever I make edits to the file with the preview open. It does eventually render (as it did while I was typing this). My entire graph is 24 nodes and around 30 edges. Also using 0.3.5 on 1.76.0 on windows 11.

Any news for this? Having the same issue.
