Thank you!
Problem seemed to fix itself?!
After I sent the previous note, I restarted my computer (seemingly for the 100th time). I was not staring at my screen the full time but it appeared to skip the Lock Screen and went directly to the sign in screen. I clicked sign in and it took a bit longer than usual, but it allowed me to enter my password and let me log in.
Happy it is working, but nervous it will happen again. I will keep your post saved just in case. Thanks again.
