Thank you @argentum, I have tried watching multiple different tutorials on making this work and my first few tries I was trying to combine their methods to no avail. I had given up until my computer crashed today and I lost hours of work on a note that had been replaced entirely with some kind of colored special character (red dots). Luckily, I have ManicTime screenshots so I will be able to transcribe my work.
Let this be a warning to those placing important information in these notes. After that, I decided I needed backups and since version history is so valuable, and since people seemed to be able to get this git backup working with the new plugin, I figured I’d give this one last go.
The link you provided, followed exactly step by step, works like a charm. And it’s clearly explained. Very simple.
I think I will also be setting up a local automatic backup of my vault. Thanks again.
