I'm one of the developers behind Egnyte integration.
What you see is two lines that the app can use later as parts of the interface. It looks like most of the app didn't get loaded.
Does this keep happening when you try again?
Could you also mention the browser you are using?
Can you open the developer tools in the browser and go to the "network" tab before opening the app and then share what gets logged there?
If you don't know how to work with developer tools I can guide you after you tell me which browser you are using.
