Roblox studio lags when opening toolbox

Hello, I’ve run into a problem where every time I open a plugin that includes a screenGUI or GUI, it lags ALOT. Explorer and properties are fine, but toolbox isnt. It is not my computer because whenever I close toolbox or that plugin, FPS goes back to normal.
Anyone know how to solve this?

Disable the plugin… if this solves the issue then its the plugin and you can switch to one that doesn’t cause the issue.
