stuck toy? is it safe to just pull out?

i got a dildo toy with a knot on it and i finally managed to fit the knot part in and ended up letting it sit for a bit. its been almost an hour now and when I try to take it out it hurts a lot when i try to pull it back out, and I can only get it around 1/3rd the way before it's too overwhelming. what can i do?

its in vaginally, and i used a water based lube for it
