Caused by: java.lang.RuntimeException: An error occurred when trying to find the optifine jar: INCOMPATIBLE
Either there is no optifine jar file in your mods folder, the one there is outdated, or you have multiple. You need to either uninstall optifine or manually add the correct optifine jar back.
