Eric this has not solved my problems in 2021 and 2020.  I have done this fix.  I have done update - repair, I have changed my 2021 and 2020 software to old and downloaded from scratch and updated and when I first go into a program after doing all this it might save once.  I had a 2020 yesterday that got all the way from start to save to print but crashes when I try to efile.  I have done every single thing recommended and still 2021 and 2020 are broken?
