What's Wrong?

After upgrading from API access to Pro-subscription vscode extension gives this error:
Error: Claude Code process exited with code 3

I have tried everything but nothing have solved the problem yet.

What Should Happen?

Claude code should prompt me for a message without the error code.

Selecting "Run claude in terminal" in settings works fine. But then i lose the ability to paste images etc. so would prefer using the extension one :)

Same thing for me there
Just upgraded claude code to 2.0.10, accepted new terms but can't using it with vs code and extension.
Works fine in terminal but not the most convenient.

I got the same issue, I was using the extension and then it froze and I got the error code. The terminal works fine. I tried uninstalling the extension and reinstalling, tried logging out and back into claude code, still doesn't work. I also tried restarting my pc and still nothing

I had the same issue. I just reverted to 2.0.9 to avoid this issue for now, hoping to revert soon.

You can use alt+v to paste images into the terminal interface (using that for now to circumvert this bug and I need to paste alot of images)

Hey guys, I found a solution. Roll back to version 2.0.9.

Close VCS.
Delete this folder:
C:\Users\user\\.vscode\extensions\anthropic.claude-code-2.0.10-win32-x64\
Then uninstall Claude npm (run cmd as administrator):
npm uninstall -g @anthropic-ai/claude-code

Next, install 2.0.9:
npm install -g @anthropic-ai/claude-code@2.0.9
Then, open Claude in the Plugins tab, click the gear next to install, and select version 2.0.9.

It should work.

안녕하세요 여러분, 해결책을 찾았습니다. 2.0.9 버전으로 롤백해 보세요. VCS를 닫습니다. 다음 폴더를 삭제합니다. C:\Users\user\.vscode\extensions\anthropic.claude-code-2.0.10-win32-x64 그런 다음 Claude npm을 제거합니다(cmd를 관리자 권한으로 실행): npm uninstall -g @anthropic-ai/claude-code 다음으로, 2.0.9를 설치합니다: npm install -g @anthropic-ai/claude-code@2.0.9 그런 다음 플러그인 탭에서 Claude를 열고 설치 옆에 있는 기어를 클릭한 다음 버전 2.0.9를 선택합니다. 작동할 겁니다.

ㅈ0.9 버전으로 롤백해 보세요.

VCS를 닫습니다. 다음 폴더를 삭제합니다. C:\Users\user\.vscode\extensions\anthropic.claude-code-2.0.10-win32-x64 그런 다음 Claude npm을 제거합니다(cmd를 관리자 권한으로 실행): npm uninstall -g @anthropic-ai/claude-code 다음으로, 2.0.9를 설치합니다: npm install -g @anthropic-ai/claude-code@2.0.9 그런 다음 플러그인 탭에서 Claude를 열고 설치 옆에 있는 기어를 클릭한 다음 버전 2.0.9를 선택합니다. 작동할 겁니다.

I'm also using it like this temporarily.
