I have two machines running vanilla-installed TL, migrated from 2019 on both.
I have compiled with pdflatex on both just fine.
After a recent upgrade, running 'pdflatex' (i.e. the command pdflatex <tex-file> in a linux terminal) on one of them (henceforth BAD) results in the error that l3backend-pdfmode.def cannot be found.
On the other one (henceforth GOOD) everything works fine, even though l3backend-pdfmode.def is not present there either.
On both machines I have l3backend-pdfmode.def in <path-to-texlive>/2019/texmf-dist/tex/latex/l3backend/
but GOOD runs without issues without that file in the analogous 2020 folder, whereas on BAD I have to copy that file to
to fix the problem.
