claude-code - 💡(How to fix) Fix [BUG] Claude Desktop crashes ~40 seconds after login on macOS Tahoe 26.4.1 - EXC_BREAKPOINT in V8/Electron (v1.3109.0) [1 comments, 2 participants]

"exception" : {"codes":"0x0000000000000001, 0x000000011af987c4", "rawCodes":[1,4747528132], "type":"EXC_BREAKPOINT", "signal":"SIGTRAP"}

"termination" : {"flags":0,"code":5,"namespace":"SIGNAL", "indicator":"Trace/BPT trap: 5","byProc":"exc handler","byPid":33398}

"os_fault" : {"process":"Claude Helper"}

And the stack trace showed:

v8::TryCatch::Reset() v8::TryCatch::Reset() v8::CpuProfile::GetSamplesCount() v8::Context::FromSnapshot() ElectronMain start

TL;DR

The most likely fix is to downgrade to the last working version of Claude Desktop, 1.260402.0, as the issue is identified as a regression.

Guidance

• The crash is consistently reproducible and seems to be related to the recent update, indicating a potential issue with the new version.
• The EXC_BREAKPOINT (SIGTRAP) exception in the V8/Electron stack trace suggests a problem with the JavaScript engine or Electron framework.
• Given that the issue persists after a clean reinstall and clearing caches, it's likely a problem with the application code or dependencies rather than a local configuration issue.
• Downgrading to the last working version, 1.260402.0, may provide a temporary workaround until the issue is resolved in a future update.

Example

No code snippet is provided as the issue seems to be related to the application's internal workings rather than a specific code snippet.

Notes

The fact that this is a regression and the last working version is known (1.260402.0) suggests that the issue might be related to changes introduced in the updates following that version. The related locked issue #29625, although marked as invalid, indicates that others might have experienced similar problems, reinforcing the idea that downgrading could be a viable temporary solution.

Recommendation

Apply workaround: Downgrade to version 1.260402.0, as it is confirmed to be the last working version before the regression occurred. This should allow the application to function normally until a fixed version is released.
