"Successful" export produces an unplayable 132 byte .mov file

[default3d7p0i1m9nld]

Exporting from Animate the way I always have has recently started to give me a different result. The project file I'm working with is about as simple as it gets. Two layers with eight drawn frames repeated a few times. Exporting to a Quicktime video shows me a window claiming that the export was successful. But the exported file won't play or import anywhere and is only 132 bytes. I've read elsewhere here that 132 bytes is a sign that the export failed. It's just strange that Animate doesn't seem to know that.

Attaching the Animate 2020 (20.5.1) project file here. Ap

Sorry, error in posting. The last sentence there was supposed to be "Appreciate any insight!" Also having trouble uploading the project file here for some reason...

After more troubleshooting, I found that Animate projects saved elsewhere export without issue. When I pull the Animate project file out of the folder I've been organizing them into, it exports okay. No idea why, but there ya go.
