Unsurprisingly it is the gigantic EA application which breaks Sims 4 most of the times. It crashes, Steam notices non zero exit and gives up.
EA isn’t so managed so they don’t even reach MS to stop pushing alpha/beta updates to stable version of their apps via Winget. So you can guess how much they will care about Linux issues. I mean Steam guys won’t really hack their binaries to fix it so it is up to them.
It was a serious issue back then. People were wandering around on the Internet with root accounts. A lot of #linux IRC channels were kicking&banning anyone with “~root” or “root” ident with educational sentence like “Do not use root account as your ordinary account, check instructions”. We don’t see the issue widespread today since distros did very good intended “dark patterns” to push users to regular user accounts. Linux (or UNIX) “root” account is true god mode. E.g. infamous “rm” as root joke (!) could even affect Windows running WSL2, so MS had to implement special workarounds.
