Can't find file for asset / Failed to Load / UE4.19.2

Hi there, here’s my problem.
I’ve been working several days in an architectural project, opening and closing everyday with no problem. I imported assets, textures and materials, moved assets between folders and fixed redirectors, did some builds, maps and so on…
Today I opened the .uproject file and i found this log message (attached).
It seems to have lost many of the assets reference (not all of them but almost, randomly), but i can see all them in the windows file structure, I don’t know what could have happened, I moved every single asset within the engine as it’s supposed to be done so i can’t guess why the references are broken.
I know i could manually relink all them but seems like an impossible task because i have many “atrezzo” assets with thousand of textures, and i don’t know if this could happen later again.
Any help about this?, I’m in a hurry and i can’t afford redoing this.

Thanks in advance.
Note: Just in case it helps, I’m using Vray for Unreal workflow
