Yep, I’m pretty sure it’s hormones kicking in.
Sammy had the same obsession – at about the same stage actually, and I ended up getting a carpet sample (low, tight pile, very cheap) and setting it under the closed bedroom door. She pushes it around, but it stopped the damage. You may want to get several, or order some large seagrass mattes to put over things for the next few months until after she’s spayed.
I’d urge you to re-read the bunny proofing section above and just inspect your home for any tasty things you may have overlooked. If you can distract her with treat rewards to get her in play areas that are OK for her to be in, you could try that. It’s probably time for a new diggy box to get her attention. It was at this stage that I turned my diggy basket over in frustration and she went under it – for the next several weeks. Not much fun for me, but saved my carpet until she got spayed.
Freya will run to the doors every single time like they’re the holy grail, but she’ll learn that they are always closed so she’ll stop lingering if there’s something better to do.
