Bug Report: Claude Desktop — Code Tab Causes OOM Crash on Launch

Summary

Claude Desktop crashes with a V8 JavaScript heap out-of-memory (OOM) error every time the Code tab is opened. The Chat and Cowork tabs work normally. The issue persists across macOS versions and clean reinstalls.

Environment

• App version: Claude Desktop 1.2581.0 (installed via Homebrew)
• macOS: Tahoe 26.4.1 (also reproduced on 26.2 / build 25C56)
• Hardware: Mac mini (2024), Apple M4, 16 GB RAM
• Installation method: brew install --cask claude

Steps to Reproduce

1. Launch Claude Desktop
2. Sign in to account
3. Chat and Cowork tabs load and function correctly
4. Click on the Code tab
5. Interface shows placeholder blocks (gray skeleton UI), content fails to render
6. App freezes with 100% CPU usage
7. App crashes within ~8–90 seconds

Error Log (from terminal launch)

[28579:0415/165812.961578:ERROR:electron/shell/common/node_bindings.cc:185]
OOM error in V8: CALL_AND_RETRY_LAST Allocation failed - JavaScript heap out of memory

<--- Last few GCs --->
Mark-Compact (reduce) 2697.4 (2764.3) -> 2697.4 (2763.3) MB, pooled: 0.0 MB,
38.07 / 0.00 ms (average mu = 0.703, current mu = 0.000) last resort;
GC in old space requested

The heap consistently maxes out at ~2697 MB regardless of configuration.

Troubleshooting Already Attempted

• ✅ Clean reinstall of Claude Desktop (deleted app + all data in ~/Library/Application Support/Claude/)
• ✅ Cleared Cache, GPUCache, Local Storage, Session Storage, IndexedDB
• ✅ Removed vm_bundles directory (was 10 GB)
• ✅ Removed claude_desktop_config.json
• ✅ Upgraded macOS from 26.2 to 26.4.1 — issue persists
• ✅ Attempted NODE_OPTIONS="--max-old-space-size=8192" — not effective (Electron ignores it)
• ✅ Attempted --disable-gpu — app errors due to GPU dependency
• ✅ Attempted --disable-gpu-compositing — still OOM
• ✅ Attempted --use-gl=swiftshader — still OOM

Key Observation

• Chat tab: Works normally ✅
• Cowork tab: Works normally ✅
• Code tab: Immediate OOM crash ❌

This strongly suggests the issue is isolated to the Code tab's initialization or data loading logic, not the Electron shell or rendering pipeline.

Expected Behavior

The Code tab should load and function normally without exceeding memory limits on a 16 GB machine.

Additional Notes

Prior to the crash, the ~/Library/Application Support/Claude/vm_bundles directory had accumulated ~10 GB of data, suggesting the Code module may not be cleaning up old VM bundles properly. Even after removing this directory and performing a completely clean install, the OOM crash persists.

Reproducing on macOS with Homebrew install
Environment:

Claude Desktop: 1.2581.0 (f10398) 2026-04-14T17:16:40.000Z
macOS: Apple Silicon (MacBook Pro)
Claude Code CLI: 2.1.109 (installed via npm + Homebrew Node 25.9.0)
CLI path: /opt/homebrew/bin/claude (symlinked to /usr/local/bin/claude)

Steps to reproduce:

Open Claude Desktop app
Click the "Code" tab/button
App immediately crashes

What happens:
App exits with SIGTRAP (signal 5) — confirmed via macOS Console logs. The crash reporter (chrome_crashpad_handler) attempts to capture a dump but is denied by AMFI: AMFI: Denying core dump for pid 15842 (Claude).
What I've tried:

Cleared ~/Library/Application Support/Claude and ~/Library/Caches/com.anthropic.claudefordesktop
Confirmed Claude Code CLI is installed and functional from terminal (claude --version returns 2.1.109)
Created symlink at /usr/local/bin/claude pointing to /opt/homebrew/bin/claude in case of PATH issue
Fresh reinstall of the desktop app

None of the above resolved the crash. Claude Code works fine directly from terminal.
Workaround: Use claude directly from terminal.

From the terminal it works fine, but I have the same error — I open it and the Claude app closes if I'm in Claude Code. In the normal chat it works without any problem.

Same issue unusable on Mac, no option to roll back no fix for so long

[Markirov]

Same issue here. Claude Desktop 1.2581.0, crashes immediately when clicking on Code — Chat and Cowork work fine.

This is really frustrating because it completely breaks the workflow I'm paying for. I rely on Claude Code daily for an active project and having to work around this disrupts productivity significantly.

Looking forward to a fix.

Bug persists in v1.2773.0 (884b37), released 2026-04-15. Code tab still crashes immediately on selection. macOS 26.5 beta 2. Chat and Cowork work fine.

Auf #48281 einen 👍 geben und einen kurzen Kommentar posten: "Same issue on Windows 11 with v1.2581.0 (Desktop build f10398). Crash is silent, occurs ~60s after opening Code tab. See #48553 for full Windows details."
