SIGSEGV
neither files nor vanadium are allowed to install apks, if you dont give it the permission.
I think they just ment, that the app store has a special permission. If installing apps is disabled in a user profil for example, the app store cant install apps either.
(it still can in private spaces tho, because the 'no install' user setting does not work in private spaces yet, if there wasnt a change lately)
