Driver: 596.36 (Studio, April 28 2026)
Claude version: 1.8089.1

Error:

Tried: --disable-gpu, --use-angle=swiftshader, --use-gl=swiftshader
All flags either crash with same GPU error or throw "GPU access not allowed" from app code.

What Should Happen?

Claude Desktop should launch and display the main window successfully.
