I cannot find information about this anywhere on the web. I have multiple documents and text files edited in the last 1-2 weeks that have been corrupted. The files are in their original paths, with the last saved modification date, and original file name preserved.
Opening a .ods (spreadsheet) gives me this

I recently reformatted and installed an SSD, but all these documents are on a mechanical storage drive. The only thing they have in common in is they were recently edited.
I ran check disk three times, once through command prompt and restarting. No errors were found. I ran CrystalDiskInfo to verfify SMART and it was good.
I am running Windows 10 64 bit Pro.
Here is a screenshot of one of the text files. All I blurred out was the original file name my user name. https://i.imgur.com/x9Q1F3f.png
