求助:pdf-tools开着pdf时,使用hippie-expand补全会导致emacs退出

win10下,emacs 27.2,配置基于centaur emacs。hippie-expand配置如下:

(use-package hippie-exp			; Expand by fuzzy matching text in open buffers
  :bind (("M-/" . hippie-expand))
  :config
  (setq hippie-expand-try-functions-list '(try-expand-dabbrev
                                           try-expand-dabbrev-all-buffers
                                           try-expand-dabbrev-from-kill
                                           try-complete-file-name-partially
                                           try-complete-file-name
                                           try-expand-all-abbrevs
                                           try-expand-list
                                           try-expand-line
                                           try-complete-lisp-symbol-partially
                                           try-complete-lisp-symbol)))
