My chiropractor's laptop needed some attention. It was refusing to install any updates, and the troubleshooter didn't fix the problem. So, I decided to try and refresh Windows - no dice. I then created a Windows installation flash drive, erased the SSD, then tried to install Windows again - no dice. After posting on an HP forum, none of the suggestions were correct. I then decided to run Memtest86+ on the machine. It immediately started throwing errors. I shut it down, removed one RAM stick, then ran the test again. It started throwing errors immediately. I removed that stick, then reinstalled the other stick, and ran Memtest again - no errors. I shut it down, and booted from the Windows installation drive - Windows installed without any issues.
I am providing this information in case anyone runs into a similar issue. I have not seen a failed stick of RAM in many years, but it can happen.
