bug#45713: 27.1; After Package Update Cannot Execute LaTeX Commands

[Nikolaus Thiel]

A few days ago I upgraded all packages using the command U. Also auc-tex
has been updated to

    Status: Installed in ‘auctex-13.0.1/’. Delete
    Version: 13.0.1


Today I want to compile a LaTeX file using XeLaTeX
but I get the folowing error:

Debugger entered--Lisp error: (error "Nonexpansion file")
  signal(error ("Nonexpansion file"))
  error("Nonexpansion %s" file)
  TeX-command-expand("xelatex -interaction=nonstopmode %s")
  TeX-command("XeLaTeX" TeX-master-file nil)
  TeX-command-master()
  TeX-command-menu("XeLaTeX")
  menu-function-53()
  funcall-interactively(menu-function-53)
  call-interactively(menu-function-53 nil nil)
  command-execute(menu-function-53)


Thanks for your help!
Nikolaus Thiel
