AI Assistant panel does not open; selecting Window → AI Assistant produces no visible window.

The AI Assistant panel does not open in Premiere Pro Beta.

When I select Window → AI Assistant, nothing happens. The panel does not appear, no window opens, and there is no error message.

Premiere Pro itself works normally, and all other panels seem to function correctly.

Troubleshooting already attempted:

• Updated macOS to the latest version.

• Updated Premiere Pro Beta to the latest version.

• Uninstalled and reinstalled Premiere Pro Beta.

• Tried an earlier Beta version.

• Reset workspace layouts.

• Checked UXP folders and settings.

None of these steps resolved the issue.

System information:

• iMac 2021

• macOS 27.2 (Build 26B123)

• Premiere Pro Beta 27.1.0 (Build 39)

• UXP 9.4.0-local

Please investigate whether this is a UXP initialization issue or a bug affecting the AI Assistant panel on macOS.
