Import from phone to Creality Scan 4 fails

I am running into the following issue:
If I scan objects with my Otter, Scan Bridge handle and phone (OnePlus Nord 4 with Android 15), exporting them to my computer tends to fail.
This morning I successfully exported one model so I thought “Heeey nice, fixed” but alas, a model I scanned today consistently keeps failing to import. The export runs up to 100% exported and then the phone says Project Export failed. PC says Import failed. No further explanation or anything.
I am running the latest apps both on phone and PC as far as I know, had to update them yesterday.

Anyone any idea what is going wrong? Is it anything to do with the model size, or am I missing something else?

Thanks!
