Resourse error
Suddenly, I started getting this error in all renders that include these hair assets. At first, everything worked fine, but now it keeps failing with this error.
Now I'm getting this error even in old scenes where I didn’t change anything at all

That sounds as if whatever the hair is growing on has been changed - if it was saved to an asset (as with the daz figures, where it points to geometry definitions in the Data folder) then any change will affect everything based on that asset. Strand based hair (and dForce hair) are built on the vertices defining the mesh, so a change there will break the hair.
You need to tell us what hair product you're using. Normally, AFAIK, the SBHs sold in this store shoudn't bring you such an error. However, there're some body / gen hairs sold on other 3rd-party sites may bring you this issue because of the "design" ...
The problem resolved itself as mysteriously as it appeared – everything just started working the next day, even though I had restarted Daz Studio multiple times before. And yes, these aren’t standard hair assets from the Daz3D store (those work fine), they’re from third-party sites.
What it could be ?
