Basically, my project crashed when I was saving my updated assets, but whenever I try to open that project, ue4 crashes on me. Please help. How do I fix this?
What likely happened is that you saved an asset that causes a crash on load. Try to identify which assets are corrupted (Likely one of the files that crashed when you saved), and then restore them from an autosave. It may be helpful to look at your crash logs (Saved -> Logs), which may give a clue as to which asset is causing a crash.
How would I restore them?
I figured it out. If anyone is experiencing this, scroll down in your logs towards the bottom. There you’ll see the assets that are “most likely corrupt” and either delete them, or override them with a previous version of those assets in your backup folder.
