Photoshop 2020 (21.0.1) 'eating' files - macOS Catalina

Anyone else having an issue where they save a PS file and it gets to 99% and just hangs there forever? Occasionally it will sit at 0% and not move but mostly it gets to 99% then crashes, causing the original PS file to be 'eaten' and destroyed. When I restart PS and re-open the file, I just get a single layer that looks like the Bifrost bridge in Thor. Im in PS 21.0.1 - Catalina 10.15.1. Screenshot of what my files end up looking like is attached.
