I only ever got problems with my Arch install on my main PC (testing repos, updated every boot/shutdown) once, when NVidia drivers updated. On my servers, also Arch and testing repos, but updated monthly, there never were any problems.
In contrast, Ubuntu/Pop stopped booting properly after a year or so, and due to the more closed, out of the box and undocumented nature (while one knows their Arch system to the single package if one installs it themselves) it was nearly impossible to debug.
