After Effects Error: Couldn't Open File

[AJ5E88]

Hi there, 

I'm trying to export/render out an old project and I'm getting this error even though all the files are present in the location it's pointed to. 

I've tried relinking the files but it gives me the same error. Nothing has been moved since I last opened the files. 

OS: Windows 10

After Effects 2022

Need this resolved ASAP. Hope someone can help.

And what file? You have not provided the most critical information liek actual file types, storage locations, render settings, exact errors.
