Bug: pure virtual method called in QueryInterface when deactivating DisplaySettings #6423
Description
Problem/Opportunity
During shutdown, DisplaySettings::Deinitialize calls QueryInterface to get another plugin's interface, Exchange::ISystemMode. At the same time that plugin destroys and stuck in SocketPort::WaitForClosure. Looks like a race condition between 2 plugins.
Thread 7 "WorkerPool::Thr" received signal SIGABRT, Aborted.
