[BUG] WorkspaceTrustError: Workspace requires trust approval before starting a session.

Same for me!

It appears this happens only when the folder to trust contains spaces. Was able to resolve this by hypenating the folder instead of spaces between words.

Any update on this as I cannot create new workspace due to this issue

I just started working out of my computers terminal since I couldn’t get
the issue to resolve on the app

same here, so frustraiting

I just found a solution that worked for me. first if you are a macOS user press:

command+shift+H

that would lead you to the root folder then create a folder there. delete the previews folder you created. once its created click the root foolder and allow the permissions again. then it should start working normal

Same issue on Windows, and I can confirm it's specific to git worktrees (not just the base repo folder).

Repro: base repo folder C:\Users\<user>\project is trusted and works fine in the desktop app. A git worktree add under C:\Users\<user>\project\.claude\worktrees\some-worktree (branch claude/some-worktree, created by the desktop app's own "worktree" checkbox) shows the trust banner and blocks with the exact error from this issue. Confirmed in %APPDATA%\Claude\logs\main.log:

[info] LocalSessions.saveTrust: cwd=C:\Users\<user>\project
[info] Saved workspace trust for C:\Users\<user>\project
[error] Cannot start session: workspace C:\Users\<user>\project\.claude\worktrees\some-worktree is not trusted

So trust for the parent repo does not extend to its worktrees — each worktree needs to be trusted independently, but there's no way to do that (the dialog doesn't offer an approve action, only "View details" showing the same error text and "Try again", which re-triggers the same failure).

Also confirming what's noted in #9113: manually adding the worktree's exact path to preferences.localAgentModeTrustedFolders in %APPDATA%\Claude\claude_desktop_config.json and fully restarting the app does not resolve it — the session still fails with "is not trusted" for that exact path even though it's present in the list. So that key doesn't appear to be what the desktop app's checkTrust/saveTrust actually consults; the real trust store for this dialog seems to live elsewhere (couldn't locate it after checking config.json, Preferences, Local Storage LevelDB, and DIPS).

This is a real blocker for anyone using git worktrees with the desktop app's Code tab on Windows. Workaround for now: use the CLI/terminal or the VS Code extension for worktree sessions instead of the standalone desktop app.
