December 25, 20222 yr The error does not identify a problem mod. Probably the only way you will find it is to experiment with removing mods until the problem goes away. (Backup your world before removing mods). Start with optifine and any other "optimisation" mods you have. Boilerplate: If you don't post your logs/debug.log we can't help you. For curseforge you need to enable the forge debug.log in its minecraft settings. You should also post your crash report if you have one. If there is no error in the log file and you don't have a crash report then post the launcher_log.txt from the minecraft folder. Again for curseforge this will be in your curseforge/minecraft/Install Large files should be posted to a file sharing site like https://gist.github.com You should also read the support forum sticky post.
