发生场景
Source(s): https://github.com/anthropics/claude-code/issues/28421 , https://linux.do/t/topic/1645480 Status: reported fixed by source, not reproduced by us.
问题
After an auto-update the Claude Code extension fails to activate and shows this error; reinstalling does not help.
报错原文（已脱敏/规范化）
command 'claude-vscode.editor.openLast' not found
如何确认是这个问题
Extension version is 2.1.53 or 2.1.55 and the error appears on activation.
根因
Regression in extension versions 2.1.53 and 2.1.55 (reported on Windows; a Cursor user reported the same).
修复步骤
- Extensions -> Install Another Version -> 2.1.52, then restart the editor → expect: panel opens.
- Or update to 2.1.56+, which a commenter on the issue says fixes this crash.
- (Our suggestion, not from the sources) disable auto-update for this extension until a fixed version is out.
如何验证
The Claude Code panel opens and claude-vscode commands register.
试过没用的办法
Reinstalling the same version.
