so there's something strange happening to my steam ui. i downgraded steam to 1682573004 and for some reason the old ui did infact work but it still shows the countdown banner. do i need to downgrade it to the december 2022 version or it's normal that this happens (and yes after i downgraded steam i added the cfg) and aslo steam says that im offline so there's no possibility to download games and use friend list. am i doing something wrong here?

so i have been trying to use this guide since maybe in the future or someday i want to use this laptop to play old games really. however i got to the linking steamapps to steamcmd section but whenever i input the command in steam cmd it says "commnand not found: mklink" (btw unsure to where to put this question so yeah :/
