What is the behaviour in Path of Building?

Opening the build the error message as seen in the image pops up. This only happens with this specific build, the other builds I opened do not exhibit this behavior. I have attempted re-installing path of building, yet the error still persists. I have also attached a zip file containing the build.
Self-Cast Crit.zip

How to reproduce the issue

Not having a gem level (deleting the level and causing it to be blank)

Character build code

Unable to provide character build code

Screenshots

Inizia aprendo la build allegata Self-Cast Crit.zip e riproduci il problema dopo aver lasciato vuoto il livello della gemma, quindi confrontala con le build che si aprono correttamente. Il problema è risolto quando una build con il livello della gemma vuoto si apre senza l’errore segnalato.
