Puppy potty training regression

Looking for advice on potty training regression. My pup is about 10 months old (give or take, I adopted her from the shelter I work at when she was 6 months old, but she was a stray so it’s not given that she’s exactly 10 months old now).

I have experience potty training since I have a 5 year old Aussie, but this never happened before. My new pup is having accidents overnight often or early in the morning suddenly. She basically came potty trained and didn’t need much direction on holding it or when the right time was to go. She always went outside with minimal accidents inside. We didn’t have to use puppy pads at all. I just crate her when I’m at work during the day and I come home on the longer days so she can get a potty break during my lunch.

Crate training has been great since I’ve only had to do it during the day, but lately it seems like my pup has had an extremely sensitive stomach and can’t hold anything overnight. I keep waking up to accidents in our kitchen and it’s so frustrating. She doesn’t potty in her crate at all so I’m considering putting her in there at nights to encourage her to hold it again. My main concern is if it is bad that I crate her at night when I have to crate her during the workday too?

Side note- there hasn’t been many changes to her diet or schedule to prompt her to have more accidents. I did read that potty training regression can happen and it’s normal around the 7-9 month mark. I’m accepting that maybe my pup just needs to be reminded on what’s acceptable and restrict her freedom a bit at night..
