Is there a utility to reformat the physical memory on my ipad?

Is there a utility to reformat the physical memory on my ipad?

I have tried "erase all contents & settings" several times. I reset the ipad a few months ago to clear possible malware causing it to crash regularly. I can flush the memory or restart. Apple support & certified service centres had nothing else to offer.

LocalStorageFileProvider has invalid kernel address faults for a couple of years.

There are many jetsam errors in analytics for standard apple software. The fault affects all the apple apps: files, pages, numbers.

All folders & files disappear then come back a few minutes later or on restart.

Exported files (e.g. pdf, rtf or csv) that are replaced when I save a new version from pages or numbers, are still listed but gone when I leave & return to the folder.

The locations stay but move up & down by themselves.

Tags get corrupted. Sometimes they stay on the file after I remove them. They can reappear when I use the same name.

It does not affect adobe acrobat (ver. 21.02.00), which can still see all folders & files, even when files cannot.

I attach a screenshot, & have sample ips files but no upload function. Example of the kernel fault below.

I have an ipad mini 2, ios 12.5.7. The battery is still good, with 10 hours charge. It is fine for my simple word processing. Replacing it expensive!
