That doesn’t mean anything. I once had an issue where every few hours, a random application would crash on Arch Linux, but not on e.g. Debian or Windows. But this wasn’t an Arch issue per se, but was instead related to an UEFI overclock setting (which defaulted to on). After turning it off, everything worked fine.
So while it seemed like an Arch issue, it was actually hardware/overclock related, it’s just that the other OS wouldn’t run into the trigger for the crash.
