Problems extracion file

New Here ,

Goodmorning everyone, I'm having a problem with Adobe Lightroom Mobile. every now and then, it happens to me that it gives me an error when exporting the photo I would like to save on my mobile all this happens to me every time an update comes out. I tried to disconnect, uninstall and reinstall the app, but nothing, and as if the app allows you to save it once and then that's it. my smartphone and a xiaomi redmi note 9 pro, until the last update everything was fine. I do not think I have lost the raw files of the photos, perxhe if I try to export it in the original raw format it exports them to me. thank you so much.
