I have installed the latest OS version, Debian Bookworm_KDE R2 and the Pi 4C+ still freezes after 10-20 minutes of inactivity. The USB keyboard and mouse are dead. Disconnecting and reconnecting does nothing. I have disabled all power save functions. No screen sleep, no hibernation mode.
Hello, I have the same problem; everything freezes and I can’t wake up the Rock 4C+. If anyone has a solution, I’d be very grateful. I have the latest official version installed.
