glibc is a core component of your system, almost every program in your distro is built against an specific version of glibc, as they use C one way or another, so you’ll break everything if you try to change the version your system expects, sorry to hear that.
I’ve recently updated my system so I’m on the latest version of glibc, which is not on mint yet. I need to setup a system to build the game against an older, more available version of glibc. Unless you’re on a rolling release distro e.g. arch, it’s easier run the windows version through lutris (proton/umu needed for vulkan),
Thanks for reporting, the System Requirements section was outdated
