@dyiing Thanks for the last recommendation. I deleted the "1.19 Aristois" Executable Jar File in my "1.19 Aristois" version folder and then ran up minecraft. It launched without the same error. Appreciate it.
After restarting my PC and changing nothing else, it seems to have fixed itself.
I can't seem to recreate the process of the lag/disconnection anymore.
This is odd because I've tried restarting my PC prior to the overnight restart.
Either way, it seems to be working fine and if the issue comes again, will be sure to keep extra attention to the details and such.
Thank you for your time either way!
It's most likely caused by your launcher if you're not using an official launcher. We cannot help with this issue in that case, because it does not occur on supported launchers.
