You create an interface, but it fails to load.

 A memory circuit breaker error occurs when an interface consumes too much memory on the server. This can happen when the interface is storing too much data in local variables or when the interface component is looping over too many items. Both of these scenarios can cause excessive memory allocation and garbage collection, which can degrade the performance of the interface and the server. Therefore, the possible root causes of this error are C and D.
