Unreal crashed (not sure why) and when I loaded it back up my character blueprint failed to load. I’ve restarted my system numerous times and tried deleting the unreal cache folder as well as the intermediate and saved folders from the project.

Never seen that one but did you try any of the Solutions already posted on AH?
Yeah I used those threads initially to troubleshoot but it didn’t work. I’m reinstalling the engine now and updating to 4.16 to hopefully fix it.
You can try the following (make a backup of your project folder before or have it in source control). This helped me with UE 4.19.2:
- Delete all derived folders & files inside the Unreal project folder (leave only Config, Content & Source folders, and .uproject file).
- Re-open Unreal - from the launcher or .uproject.
- Generate your IDE project files (Win: via Explorer context menu; Mac: Via Unreal)
Best,

Hello, do you have a solution?
Unfortunately none of these worked for me, has anyone found a solution?
Encountered the error transferring a project to an external harddrive for use on a laptop upon reoppening was receiving a large list of files with this error.
Did you find a solution? Just instantly lost HUNDREDS OF HOURS of work to this error.
Did you ever find a solution? I know it’s been over two years
did you find one?
Did you try my suggestion above, deleting all but the mentioned files (also deleting any visual studio files) and recreating them via the explorer context menu after step 2?
This might help someone - it might not. My error was caused by changing the position of an actor and not saving the level before a push.
Unfortunately I have no solution to offer. I had to re-save and push the level lacking the actor for the error to disappear.

I encounter this problem , and solved it by replacing the Broken file by a backup file in Saved/Backup folder.

I had this problem, it just suddenly appeared on all versions of my project from different dates. I tried everything, deleting all cache folders for UE4 and VS, deleting the .vs files, reinstalling ue4 source build, turning off plugins.
What solved it in the end for me, was deleting the config folder! So if you get a lot of loglinker errors suddenly and c++ classes not getting found, try that!

I found this forum post and will revive it appropriately just in case anyone is still lurking at this topic. I found the solution and for me, I was working with Visual Studio Code and it turns out running the WRONG build task will cause this problem.
I originally ran the “Win64 Development Build” and then this error happened when I re-opened my Unreal Project. The task I was SUPPOSED to run was the “Editor Win64 Development Build”. After I ran that on my Visual Studio Code and then opened up my Unreal Project, everything that was missing from the map was restored.

Deleting the config folder also fixed it for me.
Beware that deleting the entire config folder will also reset any project settings you’ve changed (game mode, maps, input, etc). You may want to keep track of important project setting changes before doing this.

I caused this error by improperly deleting a blueprint that I had just used “Import into level” to create.
I fixed it in this manner. I reimported the fbx meshes using “import into level”, left the file names the same, and then fixed up redirectors. I saved and closed down the project. Upon reopening, there were no errors.

I tried the above and it didn’t work, however, I used the Editor Rebuild option and this worked for me. Fingers crossed it helps someone else.
Hi, i tried start UE5 from the editor (VS) and the build resolve the problem to me.
