My preamble:

\usepackage[utf8]{inputenc}
\usepackage[english]{babel}
%%\setmainlanguage{english}
%\usepackage{biblatex}
%biblatex-spbasic Herbert Voss
\usepackage{xurl}
\usepackage[style=biblatex-spbasic]{biblatex}
\usepackage{libertinus-otf}}
.... more without relevance to the question

  Do you need also the selected stuff in the DOCUMENTS?

This might be relevant?
from
https://wiki.lyx.org/BibTeX/Biblatex).#toc8
Using Biblatex with polyglossia (XeTeX or LuaTeX with non-TeX fonts)

If you use the polyglossia language package, you will need to manually 
load the polyglossia package and set the default language manually in 
the preamble just before the \usepackage of biblatex, as follows:
\usepackage{polyglossia}
\setdefaultlanguage{english}
Substitute english with the main language of your document.

Thanks
Wolfgang
