    • Installing the latest version of Forge 1.15.2(31.2.55), appears to install just fine but it crashes Minecraft on launch. The recommended version does not fully install ect. Images for context: https://imgur.com/end2JkU (recommended version) https://imgur.com/uMXsapx  (latest version) Here's what I've already tried - Re-installed java - Using a VPN - Deleted .minecraft and re-installed minecraft entirely - Tried other versions of minecraft forge eg; 1.13, 1.12, 1.17 and they all work. Here's the installer log for 1.15.2 (recommended): JVM info: Oracle Corporation - 1.8.0_251 - 25.251-b08 java.net.preferIPv4Stack=true Found java version 1.8.0_251 Extracting json Considering minecraft client jar Downloading libraries Considering library net.minecraftforge:forge:1.15.2-31.2.0 File exists: Checksum validated.
