The MiKTeX console reports that I need to synchronize my user and admin updates. But the way it wants to do this is to remove miktex-qt6-bin and keep only miktex-qt5-bin. I tried that and it was disastrous. I could no longer compile files or open the MiKTeX console at all. I reinstalled MiKTeX, twice.
Both reinstallations worked but produced this warning
The following issues were detected: 1: major issue: User/administrator updates are out-of-sync.
After the first reinstall I was able to compile documents. But the console told me to request updates in User mode, and when I did that it crashed my MiKTeX again, as described. Error messages said it needed qt6-bin.
After the second reinstall I refused the updates. Now I cannot compile documents but I can open the console. The package manager reports I currently have miktex-qt5-bin packaged 3/8/2021 not installed, and it reports in red type that I have miktex-qt6-bin packaged 1/27/2024 installed today by Admin and also by User, and labelled as Obsolete.
UPDATE: I opened the Console in user mode, where the package listed miktex-qt6-bin as being installed today both by Admin and by User. I said to remove it. After that, the package manager listed it as installed only by Admin. I hoped that was good news. But in fact this crashed my LaTeX installation as before, and I can no longer open the Console at all. I can reinstall for a third time today but I see no way to actually fix it.
Here is a screen shot of the current situation, after a third reinstall

What can I do to get it working?
