So when I try to play modded Minecraft through Twitch when ever I start it up it always says "The version you are trying to play inherits properties from an unknown version.". I did have inactivated windows about a week ago but I activated it and it still gives me the message. I have tried the jar launcher before but the game either crashes or gets stuck while loading. I have completely removed Minecraft and Twitch from my PC exept one file for minecraft which my pc always made me skip it then re-downloaded it and I still got the message. I made a new account which didn't work. I have done just about every method to fix this but none have worked for me. I am trying to do this with the FTB Revelations mod pack but I have also tried it with FTB Beyond, All The Mods 3, FTB Continuum, FTB Direwolf 1.12, and FTB Skyfactory 3. Lastly when I open the Minecraft window after hitting play in twitch it says "(unavailable)" before the version which is "forge- 14.23.2.2627".
