Urgent issue with project size stopping me from doing new update

Futher update

I cannot build HLODS now for some reason

I get this error

While trying to load package /Farm_v1/ExternalActors/Farm_v1/4/FR/SBTCU0WJ9XXDHMRL7N9UI2, a dependent package /Farm_v1/ExternalActors/Farm_v1/7/XT/AGP4DZL6K8KN2WKNHNJ3W5 was not available. Additional explanatory information follows:
FPackageName: Skipped package /Farm_v1/ExternalActors/Farm_v1/7/XT/AGP4DZL6K8KN2WKNHNJ3W5 has a valid, mounted, mount point but does not exist either on disk or in iostore. The uncooked file would be expected on disk at ‘C:/Users/USER/UEFN/Farm_v1/Plugins/Farm_v1/Content/ExternalActors/Farm_v1/7/XT/AGP4DZL6K8KN2WKNHNJ3W5.uasset’. Perhaps it has been deleted or was not synced?
