It looks like is a different bug. (probably even in Emacs, when
calculating relative path)

Assuming that your `org-preview-latex-default-process' is using the
default value of 'dvipng, does it help if you change the image convertor
command to use absolute path?

(plist-put (alist-get 'dvipng org-preview-latex-process-alist)
	   :image-converter
           '("dvipng -D %D -T tight -o %O %F"))
