The "learning wall of embarrassment" is one I run into often.
When I know enough about something and can start doing stuff with it — that is when I run into that wall of feeling embarrassed for trying a thing I am not good at.
Language learning most recently and acutely: There is nowhere to hide when I try to shape words that I have just forgotten.
It is a literal failure in communication.
I acutely do not enjoy that.
My work then: Be ok with failing to make myself clear.
