No. I've never had a cast like this.
Cats sleep, like, 20 hours a day. They're eating, shitting, or playing the other 4. There is no cat who will say awake all day and sleep all night.
However. I would suggest a couple of things:
Put a few boxes around where you spend your time during the day. Once you figure out her favorite box, take up the others. That'll be her safe space - don't bother her when she's in it - and you may find she spends more time around you during the day just because she's in her box.
Invest in a variety of toys: fuzzy balls, crinkly balls,cloth mice, feather darts, and ping pong balls... they're cheap. Play with her with them. One or two will eventually clearly be her favorites; you can put the others away. If you have hardwood floors, ping-pong balls are the best, both foot playing with her and her playing by herself. If she takes to ping pong balls, count yourself lucky: these are the ultimate self-play toy. Not a cats like them, and they really only work with hard floors.
Do try to make time to play with her. I know, you said she disappears. Try treats to coax her out. Get a cheap Tupperware container, put treats in it, shake it and train her to the sound. You should be able to coax her out with that. Treats aren't food, but a few Party Mix isn't going to hurt her.
Once she knows the treats sound, and comes for them, start giving them at exactly the same time, every day. After a while, she'll come to you for them around that time. Cats have pretty good time sense.
Get one of those treat puzzle toys, that she has to manipulate to get the treats out of. Any version that works for you is fine. This can keep her entertained for a half-hour, after which it's chillax and nap time.
If you time it right, you have her treat time right before your bed time, and you'll get a couple of hours of peace.
If she learns play time is during the day at a specific time, she'll probably stop bothering you at night.
Finally: cats are crepuscular. They are naturally most active in the morning and evening, right when it's worst for you as you get ready for work, or are trying to have dinner. But if you can accommodate play time around these times, that'll be most stimulating for her, which reduces the undesirable night time behavior.
A couple of weeks is nothing. It'll take some time, and it's possible she'll never break the patterns. Like someone else says, at that point try to find a troglodyte who's looking for a cat; there are plenty of people who prefer nighttime.
Good luck. Just, please, don't take her to a shelter. If you get that desperate, ask back here, first.
