Input and HUD Blueprints not triggering in DefaultLevel when launched from Main Menu level.

When I play my game level in Selected Viewport, all my blueprints and functions work fine. Such as an Action Input to skip matinee triggering a “CancelMatinee” console command, and UMG widgets being removed correctly during matinee.

However, when I restart the level via my UMG menus in the level, using an “Open Level” blueprint node, or open my level using an Open Level button in my MainMenuLevel UMG screen, I can no longer trigger the CancelMatinee command via the action button, press the ESC key to cancel the playtest, or use my Pause button function.

Secondly, when playing from just the DefaultLevel, my Remove UI Widgets node is firing correctly, but when I play the level after an Open Level function, this blueprint node doesn’t fire correctly and is just skipped.

Frustratingly, I’ve encountered this error while I’m doing a test-run of packing my game for a concept demonstration.
