Missing Lightwrap texture while the lightwrap texture is currently in

I haven’t played gmod for about 12 days, and when I came back on, one of my hexed model’s lightwrap texture is missing, even though I checked the vmt and the lightwrap is still there.
and I asked a few friends who have my model, and they said it’s fine for them.
I even downloaded a few backups but they still don’t work, I tried reinstalling garry’s mod and verifying the cache, but nothing changed.

I got a picture of it for example

and here’s the vmt
