This is the important part of your log: Incompatible because this component declares a component compatible with Java 16 and the consumer needed a component compatible with Java 8 But you can't just switch to Java 16, since I notice minecraft("com.mojang:minecraft:1.8.9") in your build.gradle, and Minecraft 1.8 doesn't support any versions of Java newer than 8. Further, -mods/architectury-api/files/all looks like Architectury only supports Minecraft 1.16 and up. You need to either update your mod to target a matching version of Minecraft (and then you'd be able to use a newer Java version), or give up on using Architectury in your mod.
Hi,
I try to launch up my world and then it crashes to dektop, from what I read on the log it mentions architectury.mixins but not sure whats causing it another mod or smth. Would be much appreciated if someone could help.
