Why is the right shift key on my MacBook Pro not working?

Yesterday the keys started sticking "p" "[" "'" "up" "down",

when you click on them it works "enter",

"space" -> "space + ]",

Blowing out the keys didn't help, so I decided to open them and clean them,

all keys work, but shift has stopped working completely,

"shift" was filmed due to the "up" "down" keys

p.s. I don’t know how it’s connected or not, I just installed a new update yesterday 15.1
