Error 102345 TurboTax Deluxe 2019 / Way to recover an unreadable *.tax2019 file?

[RK73]

I last worked on my return 7/15/2020 and saved the file and the ~file.  I have a few things to finish up on my return and when I attempt to open either file I get an error 102345.  The file opened up fine in July, now it doesn't.  Both the *.tax2019 files are about 10.5mb each.  Is there any way to recover my almost ready to submit file?  Did a TurboTax update make my file unreadable?  I am able to open my mother in laws return and a 2/2020 version of my return in TurboTax Deluxe 2019, but not the version from July 15.  Any ideas?

Thanks!

Thanks.  I read that too.  It seems odd to me that the file and the backup opened fine in July but won't open now.  Is there a way to roll back to July version?

Any other ideas how to recover my work?

sorry. the file is corrupt, only TT would be able to supply a fix-it tool (that assumes it's a common part of the file otherwise such a tool would not be possible).  there is no such tool.
