Thanks, it works! First, I installed ubuntu 20.04 cleanly (on VMware Workstation Player), and installed TeXLive2019. And I installed emacs, maxima, and maxima-emacs. In this environment, no problems occur (of course).
Next, I installed TeXLive2020 on another instance of ubuntu 20.04, Then, the LaTeX error occurs. Finally, I applied the patch to imaxima.el on TeXLive2020, then the error is removed. I will test some other expressions on maxima in this environment. Thanks again and regards, Tomoaki Sato (cxn00...@nifty.ne.jp) > From: "Ilya G.
