I finally managed to fix this using the answer linked here: https://askubuntu.com/questions/1500474/cant-suspend-sleep-after- upgrade-to-23-10/1502550#1502550. It was due to some broken nvidia- related symlinks.

This occurs when no peripherals (Bluetooth anything, keyboard, monitor etc.) are connected too. I have tried toggling "wakeup devices" in /proc/acpi/wakeup as in https://askubuntu.com/questions/598236/ubuntu-wakes-up-after-few- seconds-of-sleep, but disabling them all didn't prevent the computer waking up immediately. Any help greatly appreciated!
