Keyboard refuses to work suddenly

Recently, after Apex Legends Season 12 update, any keyboard input while playing in-game will stop working at random times. So far, it has happened three times already.

At first I thought it was an issue on my end, but I can still use the keyboard with other programs and even alt+tab to another.

Most recently my keyboard stop working in the middle of team fight. I can still see what's going on because the game runs normally, it just don't want to input any keyboard presses. 

Although inconsistent, any help with this problem?
