I have created a project using Expo XDE. I checked this Can't load expo app: Something went wrong but I have already enabled \"Draw over other apps\". It works https://expo.
Maybe this might be helpful to simply explain that, such an error occurs if your phone and your computer are on different networks.
I resolved this issue by tethering and that way, my two devices were not on the same network.
Which means probably you can connect both your devices to the same WiFi it should work.
