Why is my boss treating me in such a way?

Some people are like that.  You aren't going to change him so you looking for another job is your best option (likely going to be tough until things start to open again).

You could also make a list of examples and sit down with him and talk about your frustration.

Some people micromanage.  Other people are never happy.  You got both in one package, lucky you.  good thing you are looking for another job.

Welcome to the workplace buddy.  It's called work because it's work, you know?

The fact that she will praise you when she’s pleased with your work is a huge bonus. Not a lot of bosses do that, whether they yell at you other times or not. From what you say, she seems to like you, even if she has a very strange way of showing it.

To control you and manipulate you into performing high quality/volume/complexity work for unfairly low pay, discouraged from asking for a raise.

Get another job fast. In the future you will always have memories of him with which to compare future bosses.

Your boss is an incompetent bottom homosexual who cannot defeat a mindset that requires him to exert the same control over others that gets exerted upon him when he is submissive to the sexual prodding of another stronger dominant gay male. He has a misogynic relationship with women only because he truly wants to be a woman. In treating you the way he does, he is attempting to find out what makes you tick, what your limits are, and do you cry. He wants his spirit to emulate yours when he is being reamed by his lover{s}.

Maybe he wants you tp quit

Perhaps he is not a good boss.

It may be his way of getting you to look for another job. If you quit, you will not be able to claim unemployment benefits, and there will be no charge against his record.
