I have the same issue too. Fork conversation from here and Rewind code to here does nothing when using Calude Code VSCode extension.

Still seeing this with 2.1.38. The logs show

Same, for some reason does not work in one of the projects (but works in others), here are logs

Same failure here, sometimes works sometimes fails silently (no idea where are the logs). If I try to load the conversation in another tab it shows empty, therefore that alternative route does not works in those cases.

same. can someone please vibe-fix this.

Same issue.

It was a regression few versions ago, I remember it was working fine but then broken. Affects a lot my work because I cannot fork anymore and save tokens on initial analysis. I have to repeat analysis again wasting time and tokens for nothing.

Same issue.

What helped me:
The root cause is a Windows Read-only attribute on the .claude/projects/ directory. Try this in PowerShell:
attrib -R[+] "C:\Users\\(your username)\\.claude\projects" /S /D

I had the same session not found error and restarting VSCode fixed forking for me

Same issue for me. @AlexLMeow I also found that restarting VSCode fixes forking but only for a bit before breaking again.

Specifically, clicking fork, or rewind or any of those buttons there just simply does nothing... no new chat, no error message.

Yes, I am stunned how this is still broken. Even completely restarting VSCode doesn't fix it for me.

Same issue. The fork and rewind buttons seems to stop working after a certain amount of forks have been made or messages sent. The only fix is to restart VSCode, but the fork and rewind buttons will eventually stop working again.
VSCode on Windows 11, Claude Code extension v2.1.71.

Restarting VSCode used to work for me, but is now also permanently broken, failing around 95% of the time silently. Switched to the CLI which stopped displaying thinking and can't even stream thinking in real-time. It would be great if at least one frontend worked reliably with the entire feature set.

I have what I think is the same issue on Ubuntu. "Fork this conversation" usually doesn't do anything until I refresh vscode. This is a deal-breaker feature for me. I've given up on the vscode extension in favor of the CLI just for the ability to easily do /rewind.

Yes, I got the same in Ubuntu. Seems for Windows is mostly fixed but tried a Linux machine recently and got the same. Worth checking on Linux too.

and it got worse in windows now. Almost not working at all, only rarely. Sometimes opens a fork but appears with trashed context. Not good.

Doesn't work for me as well on mac

What is the state of the VSCode extension, has it stopped maintenance? Why there is no one fixing it? What the heck is anthropics team doing?

+1

same issue，help！

hey I think it fixed, first check if you can update the extension or is there a restart button for extension just press it. Then restart the vscode as well after that I be able to fork a conversation
