I hear you. During 2020 I tried to work on my patio and it just didn't work, especially since it faces west. Once the sun moved over the house, game over.
You need a sun shield of some sort. You can buy one, or it wouldn't be hard to make your own. I know this works because I used a sheet of cardboard for part of a day and it worked great. I just didn't want to spend the time or money on doing anything more.
