Windows update encountered an error - 0xc1900223
I am using Windows 10, version 1909.
We are currently at 22H2, you may want to rebuild your bootable USB installer with Windows Media Creation Tools and then move forward with reinstalling the OS after backing up all essential data onto a portable drive.
Another step before reinstall is to confirm you have the most recent BIOS version.
That error is a rather generic error.
Try the fixes

and if that doesnt work then you're looking at a total wipe and reinstall using the most current image available from Microsoft.
