After Installing plugin Epic Games Launcher always immediately crashes on startup

Summary

I recently got this plugin called Tick Optimization Tool Kit.

In the Epic Games launcher I clicked install to Engine and immediately the launcher crashed. Now right as I restart the launcher every time it immediately crashes. The plugin is not in any of my engine/plugin folders. reinstalling and restarting does not work. i’ve contacted the seller and waiting a response but was hoping to see if anyone might have a solution. much appreciated
