Unable to load landscape

Hey for some reason my landscape unable to load, the error is:
Unable to load package ‘/PEOJECTNAME/ExternalActors/PROJECTNAME/5/48/C7R8M9IX7SB7M3HSVJ8T8I’. The end of package tag is not valid. Check that the file is of the expected type and not corrupted.

Can someone help me what can I do?

Hello,

You can check to make sure that the file, itself, is not corrupt by trying to use it in a completely different, empty project. If you get the same error, then the file/landscape/object/asset/whatever needs to be replaced.

I just checked and the file itself corrupted indeed, what do you mean by replacing the file? thanks in advance!

You’ll need to use a different landscape material.
