Scan documents with iPhone 13 pro

Hello , I try to scan document with PDFscanner ( App of OCR ), I can scan 1 or two pages sometime and new message appeared "Could not import from "IPhone de Sylvain16400 The device was disconnected" . Sometime I can't scan at all , the first time I think it was the app PDFscanner and I try to do with Pages too and same problem appearing. I follow many troubleshooting , my phone is on same wifi , wifi and Bluetooth open , no VPN , I try with cable nothing better.

After many try I think the scanning for documents is just at the limit of camera changing ( to be in Macro mode or normal mode ) and I think it made scanning mode crash . It have solution to lock the phone on normal camera to continue my trying ? or solution to made my phone doesn't disconnect when I scan my documents ?

Have a nice day !
