What's Wrong?

Title: [BUG] Claude Desktop fails to launch after auto-update to app-1.11187.4 on Windows 11 (rollback to 1.11187.2 fixes it)

What's Wrong?

Claude Desktop stopped launching after it auto-updated to version app-1.11187.4
on the morning of 2026-06-08. The previous version, app-1.11187.2, launches
normally. The folder app-1.11187.4 was created at 2026-06-08 09:10, which
coincides exactly with when the app stopped launching.

After deleting the app-1.11187.4 version folder so the app fell back to
app-1.11187.2, Claude Desktop launched and works normally again. This isolates
the broken version: same machine, same user profile, same install — only the
version differs.

Steps to Reproduce

1. Have Claude Desktop installed (per-user install under the user profile).
2. Let it auto-update to app-1.11187.4.
3. Launch Claude Desktop from the Start menu shortcut.

→ App does not open.

1. Stop all claude processes, delete

%LOCALAPPDATA%\AnthropicClaude\app-1.11187.4

1. Launch again → app falls back to app-1.11187.2 and opens normally.

Expected Behavior

Claude Desktop should launch normally after auto-updating to app-1.11187.4.

Affected Version

• Broken: app-1.11187.4 (auto-update, 2026-06-08 09:10)
• Last working: app-1.11187.2

Environment

• OS: Windows 11 [BUILD: ____ — siehe Befehl oben eintragen]
• Note: machine was in-place upgraded Windows 10 → Windows 11 ~1 week before

the issue; Claude Desktop worked fine on Windows 11 until the 2026-06-08
auto-update.

• Install type: per-user (classic installer), %LOCALAPPDATA%\AnthropicClaude\app-*

Workaround

Delete the app-1.11187.4 version folder; the app falls back to app-1.11187.2
and launches correctly:

Get-Process claude -ErrorAction SilentlyContinue | Stop-Process -Force
Start-Sleep -Seconds 2
Remove-Item -Recurse -Force "$env:LOCALAPPDATA\AnthropicClaude\app-1.11187.4"

What Should Happen?

betroffen sind offenbar Maschinen, deren Windows-Systemsprache nicht Englisch ist
