20b3 AI Super Scale greyed out.

Is it just me?

I get a lot of videos of sub optimal resolution, so I use the upscale option from the Edit page inspector a lot... Now with 20b3 is seems to be greyed out.

Right now I'm looking at a 360x640 video source. Timeline set to 720x1280 (portrait), and AI superscale is greyed out.

Sorry, no crash, so no log to share.
Literally created the project, dragged the 360x640 mp4 into the media pool (edit page), set the project to 720x1280 (portrait), then scrolled down the inspector to select the upscale/AI Super scale at the bottom, which is now greyed out.

Any ideas?

It's almost like someone made a post about this before.

Oh wait, they did: viewtopic.php?f=40&t=221048

I did look through the first couple of pages to see if someone had mentioned it before, and searched for "upscale" and "super scale", but as the other poster wrote "SuperScale", it wasn't found.
