Sorry to hear that. The first step to solving this the "Guix way" is to rollback your system, using the `guix system` command [0]. For example, you could use `guix system list-generations` to find the most recent generation of your system profile that does not use linux-libre 5.12. Then, you would use `guix system switch-generation $N && reboot`, where $N is the number of the generation you'd like to roll back to. Once your system is working again, I recommend choosing the 5.10 kernel series, by putting (kernel linux-libre-5.10) in your config.scm [1], reconfiguring, and rebooting. 5.11 is no longer available. The 5.10 kernel series will be supported upstream until the end of 2026 [2], and hopefully will not introduce regressions for your hardware. Finally, you may search for upstream bug reports, or report the bug to Linux. I doubt many kernel developers are testing on the x200 at this point, so they will need bug reports in order to fix the problem. I hope that helps.
