I was experiencing a loop where after suspending and resuming the laptop it would go back into suspend over and over again. To fix this just update /etc/default/grub and add button.lid_init_state=open to GRUB_CMDLINE_LINUX_DEFAULT

GRUB_CMDLINE_LINUX_DEFAULT="quiet splash button.lid_init_state=open"

I also had to add the following to stop errors during the update

GRUB_DISABLE_OS_PROBER=true

Then update GRUB

sudo update-grub

Update:

I found that I actually needed to replace gdm3 with lightdm to fix a different issue and this also resolved the suspend problems
