Having errors and can't play

[Riviestar]

Whenever I join the server for MC Eternal, I load in just fine, can see who is online, I can load the environment, but because of these errors, I can't interact with anything or type in the chat, send tp requests, and just play in general. But I don't have these errors in a single player world. I attempted to play in another server, and got the same errors, but different results for ability to play, it gave me errors for items instead of not letting me play. And it's not an allocation issue since I've allocated more than enough. I uninstalled the modpack and reinstalled it on curseforge but that didn't fix it. I'm not tech savy enough to know what else to do.

These are the errors :

ERROR: MisicCrafting:185: Could not resolve <staragedrawers : upgrade_template>

ERROR: Could not find Enchantment for the id openblocks:explosive

ERROR: [crafttweaker]: Error executing {[0:crafttweaker]:Tooltip.z}: null, caused by java.lang.NullPointerException
