Do you have a scene? Or an Arnold log (verbosity level = Info) ?
For xrefs, see my answer here for a workaround:

how do i post a 3ds max 2020 scene?
If the scene is not too big, you can zip it up and attach it.
But if the zip file is bigger than 2MB, you'll have to use some file sharing service like Dropbox or wetransfer
