I found it's caused by this piece of code inside my ~/.emacs.d/init.el

(use-package undo-tree
  :straight t
  :config
  ;; autosave the undo-tree history
  (setq undo-tree-history-directory-alist
        `((".*" . ,temporary-file-directory)))
  (setq undo-tree-auto-save-history t)
  (global-undo-tree-mode +1)
  :diminish 'undo-tree-mode)
