What to do now
Most likely: The local Claude Code process crashed while parsing or executing.
- Record the Claude Code version and the first stack frame before restarting.
- Try a fresh session with the same minimal input to distinguish corrupted state from a repeatable crash.
- Preserve logs and compare reports from the same version before downgrading.
These are conservative triage steps, not an official Anthropic fix. Use the issue and workaround evidence below before making a destructive configuration change.
Is this getting better or worse?
This class of problem is converging. 163 new reports in the last 90 days vs 696 in the 90 before — -77%. The open backlog peaked at 322 in 2025-12 and sits at 47 today.
Derived by counting each matching issue from its creation date until it closed. First-party
computation over the anthropics/claude-code tracker — the trend is not published
anywhere upstream.
Which builds report this
1,284 of these reports name the Claude Code build they were running, spanning 124 releases. Heaviest reporters:
- Claude Code v2.1.114
- Claude Code v2.0.76
- Claude Code v2.1.92
- Claude Code v2.1.119
- Claude Code v2.1.126
- Claude Code v2.1.71
- Claude Code v2.0.73
- Claude Code v2.1.81
Report volume, not a defect count: an issue can mention a build without that build having caused the failure. Versions come from the version string in the bug-report template, matched against real published tags.
Do these get fixed?
Median time to close is 4 days across 2,054 closures. Of the 2,054 closures with a recorded reason, 14% were closed as completed and 1,776 as not-planned or duplicate. The most recent completed fix landed in 2026-08.
