I have an Nvidia Graphics Device - GeForce MX450 as seen upper. I thougt that this is related with that. And on
sudo nano /etc/default/grub
updated the GRUB_CMDLINE_DEFAULT and removed ibt=off and now that parameter is
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash apparmor=1 security=apparmor udev.log_priority=3 optimus-manager.startup=nvidia nvidia_drm.modeset=1"
This time my computer may suspend 
But the new problem is, it now wakes up with worse bugs. After wake up from suspend For approximately 5-7 minutes computer is lack of Network Connections, and I can not shut down / restart computer during this period.
After 5-7 minutes, I can shut down/reboot, but on a new Manjaro Black Screen the computer stucks & freezes.
Now after suspend my
journalctl --boot 0 --unit NetworkManager.service --follow --no-hostname
is →
