Plugin caused Critical error on this website (Astrid/LA-Studio Core)


I downloaded the Astrid theme from Envato Elements the other day by LA Studio. Following the instructions upto activating plugins, my website shows this error. I managed to fix the problem i.e. deactivating the plugin. But it’s one of the core files of the theme. I tried to create a support ticket but it needs a purchase code. I can’t find this anywhere. I tried using the ‘license code’ under the licensing but it didn’t work.

So now im stuck, anyone know where I can get this plugin from or how to update it so it doesn’t keep crashing my site?
