Mouse and keyboard don´t work in play mode

Hi! I’m starting a new archviz project in UE4.24.1 and everything works fine in default game mode. But when I change to another game mode, like first person, the mouse and keyboard stop working when I hit play. I even triyed to copy the blueprints from other projects (like a first person project) and still not working. Can anyboddy tell me how can I fix this? Thanks!

Well 4.24 has so many bugs, I cannot build a game from ti sometimes.
is the Input in the Prosject Setting Empty? And do you use Blueprint or C++ fort coding?
