Windows native desktop app: excessive latency, frequent internal errors, slow simple edits

Environment

• OS: Windows 11 Home (10.0.22631)
• Claude Code version: v2.1.90
• Platform: Windows native desktop app (NOT npm CLI — npm version works fine)

Issues

1. Excessive response latency

Simple 5-line code edits take ~10 minutes to complete. The delay is unreasonable for trivial modifications. This does NOT happen with the npm CLI version.

2. Frequent internal errors

Regularly encountering "internal error" responses during normal usage. No specific trigger identified — happens intermittently across various tasks.

3. Inconsistent/abnormal responses

Responses occasionally seem off or inconsistent with the given prompt context.

4. Native app overall instability

The Windows native desktop app experience has been significantly worse than the npm CLI version. Multiple issues compounding make it frustrating to use.

Note

The npm CLI version works fine — these issues are specific to the Windows native desktop app.

Expected behavior

• Simple edits should complete in seconds, not minutes
• Internal errors should be rare, not frequent
• Native app should perform at least as well as the npm CLI version
