I just tried, and most PDF files are processed without problems with 
mutool 1.21.  So I'm not sure we should install such a workaround in 
Emacs, for a bug that happens in some cases for some specific versions 
(1.20 and 1.21) of a specific external program.

Those who have these versions of that program can (temporarily) add

(setq doc-view-mupdf-use-svg nil)

to their init file, or toggle that value to open problematic files.
