Adobe After Effects - Can't import png sequence because "file ... could not be found"

This is something I've done a million times, yet today it seems to be an issue. Trying to import ~4000 still pngs for a movie sequence (generated from Animate CC), I import to AE as footage and as a png sequence in the Import dialog box. AE goes through the motions (it takes even my relatively new MacBook Pro a few moments to select all the files, and to then attempt to import them), but in the end keeps throwing up an error that some file (a file it shouldn't need, and not a numbered file in the sequence like all the pngs I generated and then selected).

Here's the error dialog:

I've restarted all apps and the machine, regenerated the pngs from the source, tried importing to a fresh project in AE, and made sure all Adobe CC apps are fully updated. All with the same result, that error dialog.

Can anyone help me navigate around this weirdness?

Dumb question:

Have you tried selecting just the first numbered PNG and select Open?  This should open the entire sequence of images - you should not have to select all of the images individually.

How odd! That seems to have gotten me over the hump, by gum – import was successful. No sir, not a dumb question at all.

No errors this time, either – the only remaining weirdness is that the import dialog box/file chooser immediately reopens after the import is complete. I seem to recall this happening in the past, and I didn't care because my import always worked. Maybe it's some kind of feature that looks like a bug...?

To make things weirder, I had managed to squeak one successful import in shortly before I saw your reply here. I had done nothing different – in the throes of insanity I just kept trying the same thing expecting different results (partly because I was, in fact, getting slightly different results each time). At one point in my various repeated attempts, several hundred frames near the beginning were corrupted somehow to show a stinkin' test pattern... colored bars like you used to see on TV after station sign-off in the 80s (dating myself here).

Regardless, thanks for that tip, it's really helpful – and it looks like my AE likes this technique better now. I'm back in the saddle. Thanks a million, Darrell!
