Error Saving to PNG in Photoshop

Hey all,

I'm attempting to save an image as a PNG and keep getting the error: "Could not save as [filename] because the file name was not valid." This keeps happening no matter what I name the file, whether it contains hyphens and numbers or just letters. Any idea why this is happening?

For reference, I'm working on OSX Ventura 13.0 in Photoshop 24.0.0.

Thanks!
