Ouch! That is not a good way and is likely to lead to disk corruption.

The 1st thing to try is going to a text console, with Alt+F1 though F6.

If that works, press Ctrl+Alt+Del. Try once. If that doesn't work, try
repeatedly fast; depending on config, systemd has a trap for more than
7 presses in a second that will try extra extra hard and skip some
steps before it reboots.

Either way it tells the kernel to reboot and that cleanly unmounts
your disks, avoiding corruption.

If that doesn't work, use another device to look up the sequence for
the emergency rescue key, which is known as REISUB.

0% available, 100% used. You filled up your root filesystem. That's
very very bad news and will kill most OSes.

But your later messages suggest you found the culprit and cured it by
deleting log files.
