zzz doesn't work (runit)

My system goes to sleep, then after a second of being off, it turns back on again.
zzz doesn't report any errors.

looked into it, apparently it's not zzz's fault, I tried the command "sudo sh -c "echo mem > /sys/power/state"" by itself and the same thing happens, I asked chatgpt and it thinks it's a USB 3 driver issue and that I should update my kernel (already on the newest version) and that I should update my mobo firmware.

I tried updating the BIOS and it still can't sleep but now it sends me to the lock screen instead of directly back to the desktop.

I disabled all the devices in /proc/acpi/wakeup/ and now sleep works fine.
This is the output if it matters.

Is it safe to keep them like this until there's a better fix?

with the help of chatgpt i narrowed it down to /proc/acpi/wakeup device GPP0, which according to lspci is a
00:01.1 PCI bridge: Advanced Micro Devices, Inc. [AMD] Starship/Matisse GPP Bridge (prog-if 00 [Normal decode])

I ended up fixing it by disabling GPP0, I made it persistent with a runit script
grep -q '^GPP0.*\*enabled' /proc/acpi/wakeup && echo GPP0 > /proc/acpi/wakeup
exit 0
