This is on the 5.10.0-8 kernel on Debian Bullseye with Nvidia graphics with the proprietary driver installed. I am using light-locker 1.8.0 and upower 0.99.11-2 with the desktop configured to suspend my computer on lid closures. This happens whether or not the laptop is plugged in and is a confirmed bug upstream with how the upower support is implemented.
