1 year keeps playing in middle of the night

For the past what seems like two weeks our 13 month old will wake up in the middle of the night & just try to play. At first we just left him. Figured he would just go back to sleep on his own. But he would be up like 1.5-2 hours. He doesn’t have anything in his crib besides his lovey. So then we took away his lovey. No improvement. He will just crawl/roll around and talk to himself. I finally tried to see if google could help me out. What I got out of it was to immediately shut it down. Go in there and lay him back down & tell him night night. I feel like I have a newborn again with the night wakings. He isn’t working on any new skills, it’s not his bedtime (we’ve moved it back and nothing), he doesn’t get sugary foods. He use to go to sleep so easily and stay asleep the whole night. I’m going to lose my mine 😫😫😫

He takes one nap a day. Goes down perfectly fine and stays asleep. I don’t let him sleep more than two hours. He’s up at 7/8. Nap is 12-2. Bedtime is 7:30/8.
