Back to 2 naps per day at 15 months?!

So my 15 month old moved to one midday nap several months back and was doing great. Lately she has gone back to needing a nap in the morning roughly 1.5-2 hours after she wakes! Just like when she was a young baby! So now instead of a nap from 12-2, she is napping like 8 or 9 until 9:30 or 10:30 and then again from like 1 or 2 until 2:30 or 3:30.

I also think she has been going through a sleep regression lately (she slept much better last night so maybe it’s almost done now).

Anyone else experience this?! Could us being home on quarantine have something to do with it?
