I changed to the following setting and the problem discussed here has
been fixed:

(use-package company-math
  :hook
  ;; This will enable the company-math backend for LaTeX mode
  (LaTeX-mode . (lambda ()
          (setq-local company-backends
                  (append '((company-math-symbols-latex company-latex-commands))
                      company-backends))))
  )
