What's Wrong?

System:

• macOS, Apple Silicon (MacBook Air)
• Claude Code Desktop App: latest version (confirmed via update check)
• CLI version: 2.1.92 (installed via native installer)

Problem:
When creating a new project in the Claude Code Desktop App, the download fails with the error message "Download fehlgeschlagen. Überprüfe deine Verbindung und versuche es erneut."

The internal Linux VM tries to download claude.app.tar.zst but receives 0 bytes, even though the URL is reachable from macOS (HTTP 200).

Error in ~/Library/Logs/Claude/main.log:
TAR_BAD_ARCHIVE: Truncated input (needed 139122106 more bytes, only 0 available)
CCD: All download attempts failed

Download URL that fails:
https://downloads.claude.ai/claude-code-releases/2.1.87/darwin-arm64/claude.app.tar.zst

Confirmed working from macOS terminal:
curl -I "https://downloads.claude.ai/claude-code-releases/2.1.87/darwin-arm64/claude.app.tar.zst"
→ HTTP/2 200, content-length: 40745941

Confirmed NOT working from inside the VM:
The VM downloads 0 bytes despite the URL being reachable from the host.

Tested with:

• Different networks (hotel WiFi + iPhone hotspot)
• Manual file placement in claude-code/2.1.87/
• Symlinks, PATH fixes, cache clearing
• None of these resolved the issue

Workaround:
CLI works fine via terminal (claude --version → 2.1.92). Only the Desktop App GUI for new projects is broken.

What Should Happen?

Creating a new project in the Claude Code Desktop App should work without a download error.
