Did that. Now
[article
is inserted at the beginning of the exported PDF document.
I have been using the same setup for more than ten years, and do not recall 
making any changes recently.
This behavior, possibly a bug, started between March 12, 2026 and June 1, 2026.

The first three lines for my LaTeX specific export settings are:

#+LATEX_COMPILER: pdflatex

Your solution, slightly modified, works!
#+LATEX_CLASS: none
#+LATEX_CLASS: srcartcl
No. But,
#+LATEX_CLASS: koma-article
OK
#+LATEX_CLASS_OPTIONS: 
[letterpaper.twoside=false,fontsize=11pt,parskip=half,parindent=0.5in,headings=small]{scrartcl}
#+LATEX_CLASS_OPTIONS: 
[letterpaper.twoside=false,fontsize=11pt,parskip=half,parindent=0.5in,headings=small]
OK

Or even without the []
Also works.

Thank you.

I believe that I found the #+LATEX_CLASS: none on the Org list.

Koma script

I have following in latex headers in my org files:

#+LATEX_CLASS_OPTIONS: 
[letterpaper.twoside=false,fontsize=11pt,parskip=half,parindent=0.5in,headings=small]{scrartcl}

Sometime after this past March 12th, a right hand square bracket is printed at 
the beginning of every pdf document. I have found that upon export to the .tex 
file a right hand square bracket is inserted, thus:

\documentclass[letterpaper.twoside=false,fontsize=11pt,parskip=half,parindent=0.5in,headings=small]{scrartcl}]{}
           ^

On March 12th and before the export to the .tex file was

\documentclass[letterpaper.twoside=false,fontsize=11pt,parskip=half,parindent=0.5in,headings=small]{scrartcl}{}

Until now I was looking at for errors in my init file and latex setup in my org 
files. Finally realized that I should check the *Org LATEX Export* file. Of 
course, that's not to say that my init file is perfect.
