The good news I was able to get my custom input working correctly. The bad news, every time I go to backspace a misspelling in the input field, it toggles the pause menu? When I go to shift the letter L, it brings up a black screen with a close button? I have no idea what is causing this. It does not happen when using the default VariableInput. The custom input menu I created has two field inputs for the player character's first and last name.

Enable Block Input When Visible option on the root of the UI prefab.

Thank you so much! That fixed it! Figures it was something super easy.
