I would absolutely LOVE to contact support, can you please inform me as to how I do so? If you read that longer thread, I have attempted to do so for multiple years and I have been unsuccessful in reaching a human support person through any method. The support site that gets linked points me to a phone number where none of the options will get me to help unless I want to pay for help filing my taxes which I don't.
Additionally, I've continued to look into this issue and have found that although the error states that these files are corrupt, they actually have zero content and in reality they are blank. This means the problem is not with the reading of the file but with the creation of a blank file during saving.
Your assertion that there would be more posts on this topic is inaccurate because the thread I linked is 8 pages long, covers multiple years, gets re-awoken every year, and is marked (and linked) as the solution for this issue whenever it's brought up - despite there be no resolution. After searching, all the users having this issue are (like I was forced to do multiple years in a row) being forced to re-do their tax file in order to submit it - often having to do it in a single go because whatever this issue is affects multiple versions/years and causes your saves to be blank so you are unable to pick up working on your file later. Many of the people in that thread were never helped and like me, they self reported as moving to other platforms because of multiple years of this issue. If something like this happens on one version or one save, that might be a bug or a problem - if it happens over the course of multiple yearly releases going back many years now - it's a deeper issue with the software that needs to be investigated an not continually written off as "only affects a small number of people."
