Daughter afraid to be naked after failed potty training?

My 21 month old has been showing signs of interest in the potty, saying when she has to go pee and poop, and asking to be changed.

We decided to try potty training by just being naked. It started great and she had fun sitting on the potty. Then when she had her first accident it happened to be into a vent which led to my husband overreacting and saying no no no and we think that may have contributed to her being scared of having an accident.

She started holding it all day, crying and insisting on being held and carried because she had to go so bad and yelling at herself no when she felt like she had to go. I tried to help her sit on the potty but she would scream and cry.

Seemed awful halfway through the day so we gave up and said we try again later.

Since then we’ve talked about it when she says she has to go, read stories, offered it but haven’t pressured it.

Ever since then she has hated the moment we take her diaper off and now won’t even shower just take a bath in the tub and even tonight wouldn’t get in the tub. I ended up putting swimsuit bottoms on her so she would bathe.

What do we do? I feel like let it go and come back to it later but now she has such a big fear of being naked how do we help her overcome that without revisiting potty training?

Edit to add: she’s even afraid of me (mom) being naked and hates when I go potty now
