This looks like parrot club feet to me by your photos. I would have no clue how to help it as I have no experience with it myself. I’m very sorry I couldn’t be of any more help. I would consult a vet to see if anything further can be done to help.
I agree with club feet, a birth defect. Take her to an avian vet for advice on his care. Watch closely for pressure sores on his feet. Padding the perches with vet wrap should help. Gripping perches tightly may be difficult so closely supervising out of cage time may be necessary because he may fall a lot. Allowing him to have full flight ability (no wing trims) will help when he falls off his perch. I have a baby budgie about 9 weeks old (Joey) that I hand raised that has two deformed feet. The larger back facing toes on both feet flip forward, nail pointing up. The little back toes are normal facing. Gripping a perch is difficult for her. The parent birds are normal but it turns out are siblings. I know, it's a bad breeding decision but it wasn't mine- they just did it and I have since broken up their baby budgie factory. Joey is the only one out of five chicks with both feet affected. Another baby has one deformed foot and is doing very well. My avian vet said there was nothing he could do and she would have some perching challenges but climbing should be normal. She is exceptionasly sweet and we will cherish her for life as our Special Needs baby.
Poor precious angel! Sound advice above. I hate that somebody would see this darling without warning/explaining. God bless you for carig. Here are some references...

In my opinion, any of the vets listed here should be better than a regular vet.
International contacts, too.
If none are near you, maybe you could call and ask for a recommendation for somebody in your area.
And... sometimes, distant vets will offer brief thoughts or advice...
Or... sometimes I find a place to start just by Googling "avian veterinarian near ((your location))"
Or maybe a local breeder might help... again, maybe Google?
I am so glad you're here. Look at that beautiful, trusting face!
Good luck to you!
I recommend speaking with the breeder or seller from whom you purchased the Conure. They were aware of its condition before selling the poor little dude to you. A veterinarian might not be able to correct the issue of clubfoot. The bird may be unable to climb or sit on a perch, and if so, it will need to live in a cage without perches. Despite these challenges, if you do keep him, he will still make a fine companion.
