What's Wrong?

Loading suno.com in a Claude Desktop preview tab crashes the entire app within seconds. After that, Claude won't launch at all — every attempt shows the Windows dialog "This app can't open — There's a problem with Claude. Reinstall the application from its original install location or contact your administrator." Reboot doesn't fix it. Repair (Settings > Apps > Claude > Advanced options) doesn't fix it. Only a full uninstall + reinstall gets it running again, and it happens again the next time suno.com is loaded in a preview. news.google.com and webglsamples.org/aquarium in a preview do not trigger it.

What Should Happen?

suno.com should load in the preview tab like any other site. If a page does crash the preview, it should not take the whole app down, and the app should launch normally afterward without requiring a reinstall.

Error Messages/Logs

main.log at the moment of the crash:

           while checking the machine-level package status. The application cannot be started.
           Try reinstalling the application to fix the problem.

Get-AppxPackage still shows the package as Status: Ok, and Get-AuthenticodeSignature on vk_swiftshader.dll returns Valid (Anthropic-signed), so the install is not corrupt. HVCI is off, no WDAC policy, no display driver errors in the System log, ~19 GB RAM free at the time.

Steps to Reproduce

1. Open Claude Desktop on Windows 10 Pro 22H2 (Claude Desktop 1.32352.1.0, MSIX from claude.ai/download).
2. In a Claude Code session, open a preview tab.
3. Load https://suno.com in the preview.
4. App crashes within seconds.
5. Relaunch Claude -> "This app can't open" dialog. Reboot -> same. Repair -> same.
6. Uninstall + reinstall -> app launches. Load suno.com in a preview again -> crash again.

Workaround: don't load suno.com in a preview tab, or launch with --disable-gpu.
