Please Help, unreal was working fine but then due to accidental power outage I think I am getting this error.

have you tried clearing the binaries and intermediate and then rebuild the code.
Go back to a previously good copy from a VCS if you’re using one…

I tried by removing the binaries folder from the game files ,it re-compiles the visual-studio code but if i again compile from the unreal editor it shows the same error.

Removing the intermediate folder from the game solved the issue . Thanks for the help
