Problem with Archicad Datasmith export

Since few days, when I export a Datasmith file from Archicad (25 or 26, it's the same), an error window appears:

"An error occurred. If the problem persists, please report this error to Epic Games".

I think the problem is due to the Archicad library elements, because with an Archicad drawing without library elements this does not happen. I work with an Apple laptop, with Monterey Operating System.

I think I changed the default path of the temporary OS folder where the assets are located.

Thank you so much for the advice!
