I've been storyboarding for a while and suddenly I reopen photoshop and it looks like this. I'm not sure what happened but it also won't let me revert the file.
all the layers and the timeline is gone. Unfortunately, I'm on a time limit and need an answer as soon as possible. Please get back to me and tell me if you have a fix. also if anyone else sees please tell me if you have experienced the same problem as me and if you have a fix. I'm begging you
There is a faint hope that it can be a video driver bug, but if it's only this file, it's most likely corrupt. There's a quick way to find out: If you can zoom in on what you see, it's corruption. If it stays the same when you zoom, it's the video card.
There's an important lesson here, that we all have to learn at some point:
Save incrementally when working on the file.
Backup, backup, backup.
File corruption is always caused by failing hardware. Always. Photoshop cannot do it. Most often a hard drive about to fail, sometimes bad RAM. If you're working directly off an external drive, loose connectors or flaky cables is an often overlooked cause of corruption.
You need to identify the failing component ASAP. Back up everything important.
