I ended up installing Sierra OS, which I hadn't done because my bookkeeping program would not have worked on it. The upgrade (although I'm still a long way from Big Sur) fixed the Let's Encrypt SSL glitch that showed up at the same time as the problems with the Chrome update. I figure they were connected. Anyway, all is fixed. Thank you everyone!
