PC crashed using UE 4.26, now files open at the time are missing

Development Programming & Scripting Blueprint

My PC locked up while I was using UE4.26.2, meaning I had to hold down the power button to force a restart. Now, after I have reopened the project all of the files which were open at the time are missing.

A level, gamemode and actor blueprint I was working on can no longer be found in the content browser, and other blueprints complain about them being missing). This leaves my game unable to start due to various errors and obviously has me quite concerned.

I also noticed that the way I had the content browser setup has also reset (folder colours and thumbnail sizes).

The files in question can still be seen in explorer, so they are there. UE4 just doesn’t know about them. How can I go about reintroducing the project to these missing files?

Any advice would be appreciated.

Weird. When 4.26.2 opens for me it flashes a search for assets dialog box for a brief moment.

If you haven’t… …maybe create a directory in the content browser, close UE, copy files into that directory and open UE. Are the files found?

Another idea would be to try to drag and drop files from the windows file explorer window into the UE content browser.

If you figure out what happened, I would like to know how you solved it. Using 4.26.2 for awhile and have not yet encountered this…

Copy CONTENT,CONFIG and your *.UPROJECT file into a new folder. Then, inside your original project folder, go into
YourProject\Saved\Autosaves\Game\ThirdPerson\Blueprints (or similar)
and try to use one of the autosaved *.uasset files to replace the missing ones. You will have to rename them so that they’ll match.

This was it, thanks! I had to use the autosave files, which meant some work was lost but that’s better than losing the whole thing.
