Tried installing version 9944 and it just doesn't work, I use the regular version NT,  the sound effects are all jumbled, I tried using ntt_development version, it tells me its too new, I tried using modbranch 2021 and now it just doesn't open at all. I have no idea what I could have possibly be doing wrong, and even before trying to change to 9944, when I was using 9940 I tried using toggle steam and it told me  "That's not a known option." I even copied and pasted the 2 directly from the list and still said that.
