Description

This is an extremely critical bug that I encounter regularly after using the chat for a certain amount of time, especially during long conversations. The issue is present in all versions, both "stable" and preview. Initially, the chat output starts lagging noticeably, and after some time, the "Continue" chat window completely freezes. Currently, the only solution is a complete restart of VSCode. If any additional information or logs are needed, I am ready to provide them, as I am very interested in resolving this issue.

To reproduce

To reproduce the issue, it is enough to use the chat for some time. In my case, it happens regardless of whether I create new chats or use the same one for an extended period — the problem consistently occurs.

Log output

Developer debug console: empty

I wonder if the above error I am now getting after updating to ollama v0.4.4 (preview) is related to this issue.

It occurs as soon as you try to launch Continue. I tried uninstalling a reinstalling, but that didn't fix it either.

Here's the error vscode throws:

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

Edit: Created a new issue #3049

In my case, it doesn’t matter which backend is used—Ollama, OpenAI, Nebius, or someone else. The extension completely breaks down and requires an IDE restart to function again.

@shashanknimje the error you're sharing here (thank you!) is separate and has been solved.

@antonovkz when this crash happens, how long are your chats? I'm trying to get a sense of what we should be testing.

Regardless, I'm aware of a few potential re-rendering problems that we intend to fix this month
