and I did not make that GUI. Then a couple days later I went to go to another game I made and it had the same problem so I thought it might be a plugin so then I turned off all my plugins and that did not work.
Also it only does it when you play the game on Roblox and not on Roblox Studio
Seems like a malicious script/plugin, I suggest checking all of your plugins and seeing if they’re safe or not. Or you could search “script” in the game explorer and search every script, if you find anything with require or any script that includes “THIS IS A STUDIO SCRIPT” or whatever, delete it. I also recommend this plugin.
