[BUG] Claude Code crashes instantly in desktop app with error script not found stream-json

Preflight Checklist

• [x] I have searched existing issues and this hasn't been reported yet
• [x] This is a single bug report (please file separate reports for different bugs)
• [x] I am using the latest version of Claude Code

What's Wrong?

claude code in the desktop app crashes instantly every time i send a message it dies right away showing claude code process exited with code 1

the cli is completely fine the exact same native binary handles stream json with no problem when i run claude -p test --output-format stream-json --verbose in the terminal i get clean stream json output and no crash so only the desktop app crashes not my system install

things i already tried and none helped
ran login again the cli 401 got fixed but the app still crashes
claude update says already up to date on 2.1.181
fully uninstalled and reinstalled the desktop app
cleared the app cache folders in localappdata

so this looks specific to the claude code that the desktop app spawns possibly related to issue 14442

environment
windows 11 build 26200
claude code native install 2.1.181 latest channel install method native

What Should Happen?

the desktop app should spawn claude code and respond normally just like the cli does instead of crashing

Error Messages/Logs

Claude Code process exited with code 1

error: Script not found "stream-json"

Steps to Reproduce

1 open the claude desktop app on windows
2 open a project folder
3 send any message to claude code in the app
4 it crashes instantly with claude code process exited with code 1 and error script not found stream-json

note the same machine runs the native cli 2.1.181 perfectly running claude -p test --output-format stream-json --verbose in the terminal returns clean stream json with no crash so only the desktop app is affected
