Summary
When referencing any of the events in the scene graph components, the return type is $unknown. This leads to visual errors regarding the type mismatch under specific circumstances. This does not affect the build of the project.
Here is the case under which I have found this issue:
I have created a custom (Event:event(t) where t : type).Subscribe(Callback(:t):void) for UMG events. After trying to subscribe to a basic_interactable_component’s SucceededEvent, which is a listenable(agent) type, the LSP has given me an error “This variable expects to be initialized with a value of type cancelable, but this initializer is an incompatible value of type event_subscription.”

SucceededEvent

Observed Result
The LSP marks the subscription as an error, while hovering over the SucceededEvent shows that it returns $unknown. Building the project does not raise any errors.

Additional Notes
While the bug report only dives into the basic_interactable_component, this issue affects other components as well.
