AI Denoise not working Lightroom Classic

First time I wanted to try Denoise, it wouldn't work as is was trying to save with the same filename.

Seems to be the case as I got a dialog box with "Save As" and then offered to save as .TXT

Restarted LR and was able to Denoise one picture. 

Ended up with a similar error when trying another picture (after the second LR restart).

This time, with an additional error message about the GPU.

Anyone with insight into this issue?

Note that it did work well for one time (and pretty quickly too).
