Lightroom 10.0 macOS - El campo de texto de marca de agua no acepta texto nuevo

I'm using Adobe Lightroom Desktop version 10.0 on a MacBook Pro M3.

I have an existing text watermark. When I try to edit or replace its text, the text field selects the entire existing text. When I type or paste new text, the original watermark disappears, and the new characters briefly flash on screen but are not retained.

The watermark editor still allows me to change font, size, opacity and position. The problem only affects the text input field.

Troubleshooting already performed:

• Restarted Lightroom.

• Disabled GPU acceleration.

• Reset Lightroom preferences.

• Tested keyboard input and clipboard in other macOS applications.

• Confirmed that other text fields in Lightroom work normally.

The issue persists in Lightroom 10.0.

Expected result: The watermark text field should allow me to edit or replace the existing text.

Actual result: The existing text disappears and Lightroom does not retain any new text.

Please investigate this issue.
