Bedtime struggles

Just saw a post about frequent wakings so I’m glad I’m not alone but I feel like I’m doing something wrong 😩

My son wakes up around 7:45am takes a nap around 12:15pm until 1:45pm/2pm and I put him in his crib awake around 8pm/8:30pm but for the last couple of weeks he will stay awake for over an hour! He has consistently been falling asleep around 10:15pm sometimes as late as 10:45pm! Today I got him out of his crib after 45 min of just laying there, bc I don’t feel comfortable leaving him in his crib for more than an hour even though he’s not crying. My husband and I thought maybe we just had to wait it out but it’s been going on for weeks now and I’m wondering if I should adjust his schedule somehow? What is everyone else’s schedule looking like?

Btw once he’s asleep he doesn’t wake up until morning but I cannot deal with these late bedtimes. Send help!
