Can't invoke TPAI from Lightroom classic on a PSD file

When I try and open a PSD file in TPAI i get the message 'PSD files are not supported in Topaz Photo AI

Select an image
Select File->Plugin Extras → Process with Topaz Photo AI, and the message opposite appears

Works fine in Photoshop

TPAI 3.0.4
LR Classic 13.4
Windows 11 Pro 24H2

PSD files are not compatible with the Photo AI Lightroom plugin.
