Only that window occurs.

Additional context
When I try to use a skill using the keyboard immediately after entering the dungeon, such a problem occurs.

If I click the action bar skill with the mouse, I can use the skill.

It only happens when I try to use a shortcut with the keyboard.

Skills 1 and 2 work normally. Pressing any other keyboard key does not work.

When I reload it works fine.

I have five level 70 characters.
Warrior, Mage, Hunter, Druid, Death Knight.

These issues only happen with death knights.
