I have this problem too.

How to cope? I don't know. It gives me a lot of stress over keeping my job too. I agree with writing things down, it helps. I have an additional problem of some gaslighting from the boss (saying to do something one way, then claiming the complete opposite, making me look incredibly stupid -- that gets me more upset than making actual mistakes).

Despite this, I do love my job and the people I work with.

I'd also say that if you can get into a routine of how you do something, that can help too. Jumping around can get problematic.

Good luck!
