I've installed 1.21.101 with the launcher before and it's been absolutely fine, but in a recent update (can't tell you which one because I don't know), it's stopped working no matter how I launch the game. 1.21.114 works alright, but I want to use 1.21.101 over 1.21.114 because the cursor is a bit buggy in that version and beyond. No, this is not an anti-virus issue; I've seen other posts with this issue being told its because of their anti-virus but that just doesn't appear to be true. The error only shows up when using the launcher though; if I'm not using the launcher it just crashes without an error
