Valkyrie Validation error when I try to start a live session with more than 65k actors

Summary

When I try to start a live edit session to try the map (a big map), an error appears: LogValkyrieValidation: Error: Failed to open zip archive C:/input/levelname-1.zip . This error appears only when the number of actors is more than 65k. In fact, I think that with more than 65k actors, the game tries to create a new level named with -1 behind the level name.
I saw a report of the same error, but the solution was to delete some actors. Is it possible to resolve without deleting any actors?
