Whites tree frog prolapsing every night for three days

[Lucija]

My frog has prolapsed every night for the past three days, I've got it back in fairly fast with sitting her in sugar water but it keeps happening, the tank is at 43 humidity / 26-29 degrees Celsius and the frog is about 5 months old, fed gut loaded crickets.

Update I've noticed she's incredibly thin compared to my other frog in the same tank which wasn't how it was at the start ://
