There you have it – it’s an unofficial plugin. The official one is the from the official ROBLOX account. You can report the plugin for its malicious intent

Hey there! I have had this exact same problem.
Here is your solution:
Look at your plugins, one of those might be a virus. I had the problem with an “Insert Character” plugin, it was fake. Ensure that you always look up who created the plugin, I suggest using AlreadyPro’s plugin for inserting characters. Send me a screenshot of your plugins if you do not have the fake “Insert Character”. Also, do you see scripts like: “Fix”, “Matthew was Here”, or just random symbols?

Okay, it is good that you realized this before it was too late. 
This is due to a virus-infested plugin
Be careful when downloading plugins. They are often intended to ruin your game
