When org-mode is called at the start of a buffer that starts with a
latex fragment, it produces an error "Beginning of buffer" caused by
attempt to call backward-char.
A minimal example to reproduce:
1. Open a scratch buffer
2. Insert text \(\Omega\)
3. Turn on org-mode
The observable effect of this bug is that org-export-string-as does not
work for strings beginning with a latex fragment, example:
(org-export-string-as "\\(\\Omega\\)" 'html t '(:with-toc nil))
This does not return an html string as expected

I tried to follow the example, but I am unable to reproduce the problem.
May you please provide more detailed steps to reproduce and share the
information about the Org mode and Emacs versions you are using?

It works on my side.
