When I use tlauncher (I have no money) fabric 1.21.11 it keeps using the fabric loader 1.8.2, and this is a problem because a lot of my mods require fabric 1.8.4, so I downloaded the 1.8.6 version, but it made it a separate version from the tlauncher fabric 1.21.11. And when I use the sperate version, VPB causes my screen to go black. When I remove it, tlauncher works just fine. How can I fix this?
