What's Wrong?

Platform: macOS, Apple Silicon (MacBook Pro)
Claude Desktop Version: 1.1348.0 (efa3fd) — 2026-04-08
Claude Code Release Attempted: 2.1.92
What's Wrong:
The Desktop app fails to launch Code and Cowork tabs. It downloads the linux-arm64 binary but receives fewer bytes than expected, causing a checksum mismatch on every attempt. All 3 retry attempts fail.
From logs (~Library/Logs/Claude/main.log):
[ClaudeCodeManager-VM] Downloading from https://downloads.claude.ai/claude-code-releases/2.1.92/linux-arm64/claude.zst
[ClaudeCodeManager-VM] Downloaded file size: 115867648 bytes, transferred bytes: 31815049 bytes (expected: 50781363)
[ClaudeCodeManager-VM] Checksum mismatch: expected=c2f7369888de4c14205925fd3ea1ecda6c81307a766a5ba04abc18df5421984d, actual=9eb75c5fc0b26a91afefd8a642178f022cc2cd9d96e213abd72b57118c45cc33
[ClaudeCodeManager-VM] All download attempts failed

What I've tried:

Retrying multiple times
Switching networks (WiFi + mobile hotspot)
Using a VPN (Japan server)

What Should Happen?

Expected behavior: Code and Cowork tabs load normally.
Actual behavior: Both tabs fail with "Download failed. Check your connection and try again."
Note: Browser-based Claude Code works fine. Terminal install via curl -fsSL https://claude.ai/install.sh | bash also works. Issue is isolated to the Desktop app's internal VM downloader. Claude code in VS code also works.
