What's Wrong?

Symptom
After launching Claude Desktop, the window appears normally, then closes/disappears after ~15 seconds. The Claude process remains running in Task Manager (renderer crashes silently while the main process stays alive). No error dialog. No in-app error message.
This started as a different but possibly related issue: previously, Desktop would launch fine but every Claude Code session immediately failed with "Claude Code process exited with code 1." After multiple resets, that turned into the current silent-crash-on-launch behavior.
Relevant log entries
From %APPDATA%\Claude\logs\main.log during the original "exited with code 1" symptom:
[info] [CCD] Falling back to installed version: 2.1.111
[info] Using Claude Code binary at: C:\Users\Carte\AppData\Roaming\Claude\claude-code\2.1.111\claude.exe
[info] [CCD] [replaceRemoteMcpServers] Calling SDK with 6 total servers { ... }
[error] Session ... query error: Claude Code process exited with code 1
at Gdr.getProcessExitError (...\app.asar\.vite\build\index.js:390:8215)
at ChildProcess.i (...\app.asar\.vite\build\index.js:390:11260)
The bundled CLI binary (AppData\Roaming\Claude\claude-code\2.1.111\claude.exe) runs cleanly when launched directly from a terminal — claude doctor returns OK. The crash only occurs when Desktop spawns it.
Windows Event Viewer (Application log)
Source: Microsoft-Windows-AppModel-State
Event ID: 4
Level: Error
ApiSet Function: QueryStateContainerItemInfo returned with Error Code: -2147020584
Error code -2147020584 = 0x80073D18 (MSIX state container error, INSTALL_PACKAGE_NOT_FOUND family). The package path Windows references (C:\Program Files\WindowsApps\Claude_1.4758.0.0_x64__pzs8sxrjxfjjc\) returns "Windows can't find" when browsed.
What's been tried

Multiple Desktop relaunches and full process kills via Task Manager
Sign out / sign in to Windows
Repair and Reset via Windows Settings → Apps → Claude
Full uninstall via Get-AppxPackage Claude | Remove-AppxPackage, reboot, reinstall from claude.ai/download
Wiped %APPDATA%\Claude and let Desktop rebuild it
Cleared GPU caches (GPUCache, DawnGraphiteCache, DawnWebGPUCache, Code Cache, Cache)
Disabled all connectors (Google Drive, Gmail, Calendar, Figma)
Tested on multiple networks (home, school with Securly filter, mobile hotspot) — same behavior on all
Switched from Windows 11 Insider Preview to stable Windows 11 Pro — same behavior
Native Claude Code CLI install at C:\Users\Carte\.local\bin\ works perfectly via terminal regardless of Desktop state

Workaround currently in use
Running claude from CMD — works fine, no issues, full functionality.
What I think is happening
The Desktop MSIX package's AppModel state is corrupted (Windows references an install path that no longer exists). Fresh installs apparently inherit or recreate the corruption. The renderer process crash on launch may be a downstream effect of this state corruption rather than an independent rendering issue.

What Should Happen?

The Claude app should open without crashing.
