What's Wrong?

Issue: The app launches but is stuck on a completely grey/blank screen and never renders.

My setup:

• MacBook Pro 14-inch, November 2024
• Chip: Apple M4 Pro
• macOS: Sequoia 15.7.4

Troubleshooting I've already tried:

• Force quit and relaunch
• Cleared all cache folders (~/Library/Application Support/Claude, ~/Library/Caches/Claude)
• Full uninstall and clean reinstall
• Checked Privacy & Security settings — no blocks found
• Launched via Terminal: /Applications/Claude.app/Contents/MacOS/Claude
• Launched with --disable-gpu flag, which returned this error:

"Error: GPU access not allowed. Reason: GPU access is disabled through command line switch --disable-gpu and --disable-software-rasterizer."

• Reset app permissions via Terminal: tccutil reset All com.anthropic.claudefordesktop

None of the above resolved the issue.

I also have NO console app logs...

The app was previously working and stopped rendering randomly.
Could you please help me get this resolved?

What Should Happen?

claude should open with no problems
