i know that bug, well it isnt actually a bug, an antivirus has detected the game launcher as a virus and deleted it, happened me to me sometimes the best way to fix this is downloading the game again and saying the antivirus that the launcher is in whitelist before opening it
This explains why the previous and most recent versions worked on my new computer and 0.8.0 didn't, it came with an antivirus installed from the factory and I don't even use it. TYSM, I appreciate your help!
