Preview of .CR3 files not working with space bar in Sequoia 15.4.1

Stopped working after the update.

Now, in order for the preview to show the .CR3 file, you must first move the blue rectangular cursor to the desired file. Then stretch the preview window or the finder window. If you don't stretch the window, you will always see a black screen. Preview jpeg file works fine.

In the bottom screenshot, after I pulled the window arrow into the finder. Before that, the preview only showed a black rectangle.
