HELP!baby only naps when pushed

As

Please help, any advice. My girl is 6 months old, and things have generally not been on the up and up this last month. She will only take a nap if she is pushed in her stroller, I have to push her through the house. Sleeping at night in her crib used to be so easy, now she rolls on belly and cries cause she can’t get back over. She wakes up at 530 in the morning from rolling over and I have to hold her in my arms till 730 am. If I try to lay her back down in her crib she will cry. It’s getting pretty exhausting. I’ve tried several times to get to nap in crib but she stays awake in there. Ugh any advice, tips, will this phase pass? Here’s my sweet girl, just took this with my new phone :)
