Thanks, I've now added the list and the bug to Cc again.

I still can't reproduce the issue with my testuser account using emacs
27.1, auctex-13.0.0 or 13.0.1, your .emacs (with the windows-specific
parts removed), the above 4 lines in ~/.emacs.d/site-start.el, and your
testdoc.tex.

Does `M-x list-load-path-shadows RET' list something?  (Maybe there's a
leftover from an old auctex install.)

Otherwise, are you able to operate edebug?  If so, please `edebug-defun'
`TeX-active-master-with-quotes', and tell me which expression signals
the error.  If it's really

        (setq TeX-expand-pos
              (+ TeX-expand-pos (length res)))

as I suspected, then you'd probably need to edebug `TeX-command-expand'
to see why `TeX-expand-pos' stays nil rather than being set to an
integer.

Bye,
Tassilo
