Would deleting a corrupted word doc save it?

I have a problem with the word docs on my ipad. basically, my ipad and phoneare synced and for the last while i wasn’t using my ipad because of school. I updated my phone to ios 17 and thought everything was good unntil i checked my files to see pretty much all of the files that i’ve saved here are gone. They weren’t saved on the cloud, only on the ipad because i only wanted them there. i realised quickly what happened and did a few things to help get them back which didn’t work because i forgot i only saved them on the ipad.

I found them in the recents tab on the word trying to get into them and save them only for them to not open with a notification tab saying that something went wrong. Despite not being on the files, they do show up when i search for them.

After downloading and buying software to uncorrupot them and not being given straightforward advice that could actuallyu help, i’ve kind of given up. I lossing my patience and sanity trying to figure out the problem so it probs wouldn’t hurt to ask if delteing one document would help get the rest back. Any advice?
