All of the above. I've created new folders on my local computer with nothing in them=this issue

I've created new folders in my external hard drive=same issue

I've created new folders in my networked shared drive (my two computers at home as view it)=same issue. 

And again, it's semi random, can't find a thread between the clients that have this issue, and the clients that don't. All proforma'd at the same time. Sometimes a fresh proforma from 22 to 23 has resolved the issue, but it means I have to redo the return.

I'm not sure why we're so focused on the external backups when a local backup should always work, and the only common thing here is Lacerte. This is a Lacerte issue. Have you experienced this specific error?
