This is pdfTeX, Version 3.141592653-2.6-1.40.22 (TeX Live 2021/W32TeX) (preloaded format=pdflatex)
restricted \write18 enabled.
---! %/Texlive/2020/texmf-var/web2c/pdftex/pdflatex.fmt% made by different executable version
(Fatal format file error; I'm stymied)
这个时报错的信息，求大神解答
把这个路径/Texlive/2020/texmf-var/web2c/pdftex/pdflatex.fmt的pdflatex.fmt删了再编译，亲测有效！
参考：https://bbs.archlinux.org/viewtopic.php?id=257216
Solved: There was a "pdflatex.fmt" on the same directory as the latex file. I deleted it and all was well.
编译入口是否有问题？
