AsyncLoading Missing Dependency

We’re started getting the following errors when running packaged builds. The asset referenced (PickUp_Core) hasn’t changed recently. This happens in all build configurations.

LogStreaming:Warning: Could not find import PickUp_Core_C.Box_GEN_VARIABLE in package /Game/Blueprints/PickUps/PickUp_Core, this is probably related to adding stuff we don't need to import map under the 'IsEventDrivenLoaderEnabledInCookedBuilds'.
LogStreaming:Warning: Could not find import PickUp_Core_C.FollowTrigger_GEN_VARIABLE in package /Game/Blueprints/PickUps/PickUp_Core, this is probably related to adding stuff we don't need to import map under the 'IsEventDrivenLoaderEnabledInCookedBuilds'.

Missing Dependency, request for Box_GEN_VARIABLE but it hasn't been created yet.

Any thoughts would be appreciated.

I need an answer to this too, similar problem

We’re also experiencing this problem but just running local debug builds. Is this related to out of date files? Not really sure what’s going on here to be honest.

having this issue as well, maybe a file got corrupted or something? Wondering if anyone in this thread ever found a solution.
