Steam Game is Currently Unavailable

hi, had the same problem today, but after searching couldn`t really find a problem. fiddled and managed to get it working, but when I loaded fmrte it told me that my fm was a different version and isn`t supported. so I`m guessing that there`s been an update of some sort. I know this doesn`t help much, but it may be the reason

fmrte supported version 12.0.2 230123
my steam version today is 12.0.3f231651
