A. Upgrade all the upgradable packages.
B. Downgrade to a known-good set of packages.
C. File a bug report (but only after trying A).
Those are your choices.
Downgrading to a "known set" of good packages is a lot of work requiring time galore.
The other option is someone else has come across this and has a solution.
You didn't mention which Emacs Version, package manager, etc.
A very good point and stupid of me. added. That said, if someone else has seen this error they'll recognise it.

What's needed is a reproduction case. There are people claiming the bug affects them with both package.el and Straight. I've not encountered the bug myself, and frankly can't be bothered to dig into it if the people who are seeing it can't provide a repro.
Then dont. This was merely asking if someone has solved it. Thanks for the link.
idk if you found a solution but i just had the same problem after a mass package update i did. To solve it, I deleted magit-* from .emacs.d/elpa (i.e. all the cached files), restarted emacs and after it re-downloaded magit, problem was gone.
