The problem has come for a long time for me.

The keyup events for key A-Z do not work in <input type="text"> in the latest version of Google Chrome (Version 79.0.3945.88 (Official Build) (64-bit)).

Only keys like ESC, Enter, Delete ... etc work.

Does anyone have the same problem?

Finally I found the reason why keyup does not work. It was because the English input of the Chinese input method "Chewing" is lightly different from native English input method.

Take typing a character "A" for example:

Native English Input Method

1. keydown
2. keypress
3. "A"
4. keyup

Chinese Chewing Input Method

1. keydown
2. "A"

Both of keypress and keydown event were not triggered.
