The screenshot of https://learn.microsoft.com/en-us/answers/questions/1339707/help-with-figuring-out-what-is-causing-waitchain-d https://learn.microsoft.com/en-us/answers/questions/1339707/... says this: > The root cause is the TV generates random UUIDs for UPNP network discovery every few minutes. That means it poses as a new device. This caused windows to add it to the device list (Device Association Framework, aka DAF) as a new device. This means now 1000s of devices (which is the same device) filled the device tree causing it to enumerate forever. Thus the "deadlock". > TaskManager uses DasHost to enumerate devices for some reason, so that hangs. > Bluetooth relies on device discovery, so that also hangs, and Settings app along with it. > Network discovery in file explorer obviously also needs Device discovery, so that also hangs.
