msvc detection bat scripts do not work.

i know this is probably like the 5th issue like this but i couldn't find a solution to my specific issue in any other ones.
sorry in advance if i didn't look hard enough and it's a dupe.
my machine has visual studio community 2019 installed, and i have vswhere installed using winget. the bat scripts still fails.

also, the vswhere command in the bat file works properly, it outputs the correct path to vs which is E:\!fuckunity\vs.
also also i just realized that maybe the ! in the path may be an issue and i'm just a doofus. though it isn't an issue with unity and executing it manually in cmd works.
i don't really want to try installing it into a dir without bad symbols because that'd require way too much effort. ,_,

hope the output below helps.

don't mind that i'm running this in pwsh, it still outputs the same in cmd.
