To check, you can e.g. run in a terminal
ls -l /home/texlive2019/bin/x86_64-linux/lualatex
If it's a symlink, it should point (with "->") to the target. Than you
can "ls -l" the target until no -> redirection is found anymore. But I
would first try the suggestion below before going down this rabbit hole.

I just noticed that your path, i.e. /home/texlive2019/bin/x86_64-linux/,
does not show up here. Can you try adding it under Edit > Preferences >
