Your BP is most likely trying to escape to find heat. A good rule of thumb is 78-80° on the cool side of the tank and 88-90° on the hot side, with a gradient in between. Ambient temps should be about 78-80° throughout the tank as well.
50% is an okay minimum humidity, but I personally feel a lot more comfortable keeping my BP at a regular 55-60% when not in shed.
The tank you're keeping her in could also be a touch too large, so make sure she has enough hides (at least 2) and decor to fill up the space cozily. A properly sized enclosure should at least have enough room for a BP to fully stretch out, but not be so open as to leave her feeling vulnerable and unsafe.
Is your BP eating? Another good indicator of suboptimal husbandry is going off feed.
I'd say, for now, adjust her temps and maybe bump humidity, then continue to observe her responses. The excessive roaming/escaping should stop once her husbandry is all good.
