Error exporting app when documnet name changes

I built an app, I can export it, no problem
But if I change the document name, when I try to export, the log provides this error:

errorexporting.log (97.8 KB)

I did copy the whole document and paste it on a new patch, ( with all the references ) and I was able to export it again…
but , after changing this new document name, the same error appers

The issue is that I am saving all my project like
Balanza03.vl and so on…
Balanza05.vl (44.8 KB)

I am on gamma 2020.2.2
