Hi Ikumi,

> 1. What is the value of `TeX-shell' in the document buffer?


Using C-h v I get the following

************
TeX-shell is a variable defined in ‘tex-buf.el’.
Its value is
"C:/emacs/emacs-26.2-x86_64/libexec/emacs/26.2/x86_64-w64-mingw32/cmdproxy.exe"
************

2. What is the value of `process-environment' in the document buffer?
>    The result can be quite long and may contain sensitive information.
>    Mask the portion which shouldn't be disclosed with "*".


No need to mask any information. Here is the output

************
process-environment is a variable defined in ‘C source code’.
Its value is

  This variable may be risky if used as a file-local variable.

Documentation:
List of overridden environment variables for subprocesses to inherit.
Each element should be a string of the form ENVVARNAME=VALUE.

Entries in this list take precedence to those in the frame-local
environments.  Therefore, let-binding ‘process-environment’ is an easy
way to temporarily change the value of an environment variable,
irrespective of where it comes from.  To use ‘process-environment’ to
remove an environment variable, include only its name in the list,
without "=VALUE".

This variable is set to nil when Emacs starts.

If multiple entries define the same variable, the first one always
takes precedence.

Non-ASCII characters are encoded according to the initial value of
‘locale-coding-system’, i.e. the elements must normally be decoded for
use.

See ‘setenv’ and ‘getenv’.

Auctex did run successfully on this computer in the past. Following your
suggestion I installed auctex-12.2.4, but not joy: the error persists.

Thanks for all your help.
