I just installed the magit package in emacs 26.3 (using CentOS 7 OS). When I start it with
M-x magit, I get the error below. It works fine for me in an older installation, and the only difference I can see is that the one I just set up is using newer versions of some magit related packages. I don't see any issues posted on GitHub related to this even though it renders magit nonfunctional, so I'm wondering if anyone has a tip on how to resolve the error.
