Another vote for taking yourself out of the "teaching" role. As much as you're trying to help, there's a good chance she's picking up on your expectations and hopes that she will soon be a better reader. Some kids might be motivated by that, but rarely when it's a parent in that role. There are other ways to help that allow you to "just be the mom" and not the teacher.
Our DD really loves Raz Kids. It's a program they use on the computer at school, and each kid has a free login and password to use at home. We're not big on screen time, but we like this program because it gives DD autonomy. She can set her own pace and pick her own books. Also, there's a mode where it reads to her while lighting up each word, which is a great way to teach word recognition. And of course, no one is watching so she doesn't feel judged. There are lots of other great reading apps and programs, too. Ask her kindergarten teacher or the school librarian for ideas. Or just Google around. Kids REALLY love reading games or programs on the computer. Especially if they don't get a lot of screen time otherwise.
In terms of her reading out loud, it really will come in time. Some kids are totally comfortable trying even though they know they're getting lots of the words wrong. Other kids are little perfectionists -- unless they know they can read something well, they won't even try reading it out loud. Our DD was like that. She NEVER wanted to read out loud, but she "read" to herself a bunch. We had no clue what she could read until one day we heard her reading fluently to her younger sibling. It's like she had been working on it in her own head for months and then "unveiled" the final product. But until that point, there's no way she would have practiced with DH or I. (I think that changed when she got to Level L or so. Basically, when she felt really confident.)
So find fun ways for her to practice by herself, and just continue to read to her every night and any other time she wants you to read. Point to the words as you're reading them (studies show that helps), but don't force her to read out loud to you. Give her a break on all that stuff and see what happens in a month.
