相同的 MWE 工作正常这里但是当我添加以下几行时出现问题：

\usepackage{fontspec}
\usepackage{polyglossia}
\setdefaultlanguage[numerals=maghrib, calendar=gregorian]{arabic}
\setotherlanguage{english}
\newfontfamily\arabicfont[Script=Arabic]{Amiri}
\newfontfamily\arabicfontsf[Script=Arabic]{Amiri}
\newfontfamily\arabicfonttt[Script=Arabic]{Amiri}
\newfontfamily\amiri[Script=Arabic]{Amiri}
