How to restore a file that has been corrupted in a computer crash
Hi, I was going to suggest version history as your best option, but it looks like that's a problem for you for some reason. Odd.
Failing that, maybe try some of the techniques in this doc - https://docs.microsoft.com/en-us/office/troubleshoot/word/recover-lost-document
Good luck. 
I just solved this, thank you PeterRising Although there is no version history on the local one drive, I tried the OneDrive for Business and even though it told me the file was not readable/accessible, there was a full version history there in the online site and I got my file. Really strange, it lost over 100 kb in the MS Pro crash, but I have it back now. Thank you for replying anyway. This might help someone else in future - check the online OneDrive rather than just your local one.
