using an older luatex file I get

luatex A-SP-WITTE-E-2022Jul18-AndersStructure.tex
This is LuaTeX, Version 1.15.0 (TeX Live 2022)

kpathsea: Running mktexfmt luatex.fmt
/usr/local/texlive/2022/bin/x86_64-linux/mktexfmt: kpsewhich 
-var-value=TEXMFROOT failed, aborting early.
BEGIN failed--compilation aborted at 
/usr/local/texlive/2022/bin/x86_64-linux/mktexfmt line 25.
I can't find the format file `luatex.fmt'!

Something must be wrong with my tex stuff
