Color eft not working with Smart Objects in Photoshop 23.0.x

Whenever I send an image from Lightroom Classic to Photoshop, turn it into a Smart Object and then invoke Color Efex, Color Efex claims to process and save the image, but then nothing new shows in the Smart Object and a window pops up that has a progress bar that’s stuck (and stays that way). My only resort is to Force PhotoShop to Quit.

Silver Efex seems to work fine with Smart Objects in PhotoShop.
