What's Wrong?

After updating Claude Code with GUI to version 0.16.0, the user interface no longer works. It just stays blank. I tried downgrading back to 0.15.0, but I’m still seeing a blank screen.

I’ve disabled, uninstalled, and reinstalled the plugin several times. I’ve restarted the computer several times—but nothing has helped.

The Claude Code [Beta] plugin works without any issues.

I’m currently using PHPStorm version 2026.1.2 (Build #PS-261.24374.185, built on May 18, 2026) on Windows 11.
