Lightroom for iPad crashing on direct import from cf express a card

I have been having this issue as long as I have been using Lightroom for iPad, since early 2020.

previously it happened when importing from an Apple usb-c to SD Card reader. this was using uncompressed raws off a Sony A7R4 from a 256gb sdcard. The fuller the SD card the more likely it was to crash when importing. the only workaround i could find on ipad os 16 was to use files import instead of direct import, this would usually work, but would also sometimes crash.

Now I am using a prograde cfexpress a reader, reading A7R5 lossless compressed raws off a sony 320gb cfexpress a card, on the latest version of LR for ipad and up to date ipad os 17. I have ~3600 lossless compressed raws on my cf express a card, and the LR import keeps crashing during import when it gets to around the 3000th picture it is copying.

When i reopen LR, it gives me error code 19700902, forcing me to force quit the app and relaunch. 

This is especially frustrating as it wastes a ton of time, as I then have to wait for all the pictures that did get copied before the crash to finish importing, so i can then delete them all, and start over. which for this many pictures can take close to an hour. This is on a 1tb ipad 12.9" ipad pro with M2.

I also tried using the import from files instead of direct import this time, doing batches of ~1000 pictures each, and this also failed in a strange manner. it copied all of the files, i can tell from how much space was used, but about 900 of the pictures were never imported, even though the space was being used, and I cannnot delete them as they were never imported.

Reading on this forum, there are many other users that have similar issues with importing to ipad lightroom, please fix this as it makes using this application incredibly frustrating. I just want to import my photos and get to work, but instead i have to spend hours waiting for imports to finish so i can delete them and start over.
