after sending them a corrupted file for the unmpteenth time , I got a response from their saying that exceptionally they are willing to accept a screenshot from my device "showing in its totality the police report".

Do you think i should stick to sending them a corrupted file, or for example I could do something like this pic i took?

They haven't declined the fact that they cannot open the corrupted file, otherwise they wouldn't be requesting another file of the said contents.

Comply with their request and stick with the corrupted file. This gives the Impression that you're doing what they ask of you.
