Thanks for the info. However, I'm not confident that has addressed the
full issue. I note that patch is from 2014. There has certainly been a
number of people report mixed installation problems since that patch
would have been applied and part of their current version of package.el.
As you point out, we don't know what happens with other package managers
like straight.el and you are likely to get this issue if part of the
built-in version has been loaded before package.el attempts to load the
new version, so that might explain these later reports.

Would seem the best approach and simplest solution is still to ensure no
org functionality has been loaded before attempting an update.
