Windows 11 sleep issues
Your PC is entering sleep, but something wakes it almost immediately; the webcam activity and KVM-connected input devices make a wake source more likely than a monitor-only problem. After reproducing it once, open Terminal as administrator and run powercfg /lastwake, powercfg /waketimers, and powercfg /devicequery wake_armed. Those commands identify the last wake source, active timers, and devices allowed to wake Windows. Temporarily disconnect the KVM, keyboard, mouse, and dock, then test sleep again. If that works, reconnect one device at a time and disable “Allow this device to wake the computer” only for the confirmed device in Device Manager. Also install ASUS BIOS, chipset, graphics, and camera updates, because Modern Standby behavior depends on firmware and drivers. If no source appears, generate powercfg /systemsleepdiagnostics and review the report. Windows Hello is not a sleep fix; its camera flashing is evidence that the system has already resumed.
Thanks for the reply.
I've disconnected the KVM and plugged the mouse and keyboard direct into the PC.
I downloaded and installed all the ASUS drivers and the firmware is the latest.
I disabled Wake on LAN in the BIOS, and on both network cards and the USB4 root device as they were mentioned in powercfg \devicequery wake_armed.
But still no joy, the lock screen comes on again a few seconds after I use the sleep option.
