After updated to version 3, global settings disappeared

Hello, i recently updated to version 3 of FREE elementor, and all my global settings disappeared and the color of my buttons changed as well. When i tried to go to the editor page in the elementor and opened the hamburguer menu, there was nothing, the menu disappeared, thats why my settings were not appearing. Also after the update i saw i notification that the data base elementor update is running in the backend and i this take too long i can clic in a button. When i clic in the button my site broken.

Also my site was consuming insane amounts of CPU because of that

I returned back to versión 2.99 and everything worked again

Please help
