I did restart and take every step to make sure it wasn't my computer. I treated it as a possible hacker so I did some simple command block to combat the hacker with another profile. After I did that I was able to join my world again. My armor disappeared and a buddy of mine couldn't see anything after we did this. We eventually fixed the issue but to add another precaution I downloaded a anti-cheat add-on by Matrix. So far by taking these precautions my world has ben able to run with only minor issues such as error messages from the add-ons. The precautions was taken in suspect of a hacker because of a log in glitched that showed the user noob1234 Hacker.
Also strangely I tried logging in a few times and when I tried signing in noob1234 Hacker popped up. After a few seconds it switched back to my Profile.
The add-ons I am using are Bath Bombs, Myth & Dragons, Horror Survival, RPG Skills, Security, Gravestone, Sparks Pets Premium, Poisonous Potato, Spark Portals, Furniture, Modern Furniture, Conquest, Naturalist 2.0, Magic Spells, Matrix Anti-Cheat (only outside of marketplace add-on), 15 Year Party Supplies, Another Furniture, Villagers ++, Weapon Fusion, and Hikers Friend add-ons.
