Moved from TexLive 2018 to 2020 and now I'm getting countless font errors

After sticking with TexLive 2018 for over two years, I decided to move on to TexLive 2020. I followed the instruction here, changed my path to point to the new TexLive directory, rebooted and so on. I ran sudo fc-cache -fv. I attempted to update the install through tlmgr, just in case, but I already had every single package installed and updated (except four that have "Windows" in their names).

In spite of all of the above, now when I try and use TexLive 2020 to compile documents that were working yesterday with TexLive 2018, I get uncountable errors, mostly related with fonts.

missfont.log shows only missing fonts:

The document’s compilation log has many more problems. It’s 1 MB+, so I’m including some highlights here.

In spite of not appearing in missfont.log, there are these errors:

! Package fontspec Error: The font "Linux Libertine O" cannot be found.
! Package fontspec Error: The font "Linux Biolinum O Bold" cannot be found.
! Package fontspec Error: The font "Libertinus Sans" cannot be found.
! Package fontspec Error: The font "LatinModernMath-Regular" cannot be found.

A more detailed version of one of those error messages is here:

A font might not be found for many reasons.
 Check the spelling, where the font is installed etc. etc.

I do have have this font on my system. In my TexLive directory tree. In fact, there are over 5300 files relating to it. Here is a small sample, cut down due to the SX character limit:

How do I fix this? In the past, I was always able to fix LaTeX font problems with sudo fc-cache -fv, but not that’s not doing the trick.
