[Message part 1 (text/plain, inline)]

Auctex works well while compiling with `C-c, C-c', but try to use
'pdfxelatex' in preview process. I guess this may due to my config with
tex-mode, and Gemini could not make it works well.  May  I get some help?
THX!

And my init_latex.el is as fellow:

I suppose you intend to force XeLaTeX usage.

This doesn't work because xelatex produces pdf file, not dvi file.
Comment out those two customizations and try the following (after you
restart the emacs session).
(1) After you open your XeLaTeX document, open the menu
    "Command"->"TeXing Options" and select "Use XeTeX engine"
(2) Type C-c C-c (for ordinary typeset) or C-c C-p C-d (for preview-latex).

If it does the trick, Change the default value of `TeX-engine' from
`default' to `xetex' via
M-x customize-option RET TeX-engine RET
. Then the customization will persist across emacs sessions.

AUCTeX doesn't have these four options. Why do you have them? Perhaps
some other package(s) offer them?

For the sake of completeness, AUCTeX has:

,----[ C-h v preview-LaTeX-command RET ]
| preview-LaTeX-command is a variable defined in ‘preview.el’.
| 
| Its value is
| ("%`%l \"\\nonstopmode\\nofiles\\PassOptionsToPackage{"
|  ("," . preview-required-option-list)
|  "}{preview}\\AtBeginDocument{\\ifx\\ifPreview\\undefined"
|  preview-default-preamble
|  "\\fi}\"%' \"\\detokenize{\" %(t-filename-only) \"}\"")
| 
| Command used for starting a preview.
| See description of ‘TeX-command-list’ for details.
| 
|   This variable may be risky if used as a file-local variable.
|   You can customize this variable.
|
`----

note the lower `p'.

Best, Arash

Thank you for the feedback. I'll close this bug.

Ah, then some generative AI like ChatGPT, Copilot or Gemini told you
the false advices, I see. Thanks, I realize that they are not so good at
tuning AUCTeX.
