fontspec 包和 asymptote 之间的兼容性问题

Question

fontspec有人遇到过该包和之间的兼容性问题吗asymptote？

在下面的 MWE 中，注释掉允许\usepackage{fontspec}正确编译和嵌入 3D 渐近线操作。

如果不注释掉 fontspec 包，我会收到如下错误

"Latex Error: ./untitled-1.tex:1 LaTeX Error: Can be used only in preamble.

 Latex Error: ./untitled-1.tex:9 Undefined control sequence."

当操作符嵌入在输出中时，也会有everypage嵌入这个词。

\documentclass{article}
\usepackage{fontspec}
