Client gets instantly kicked from server after connecting "ReceivePropertiesForRPC - Mismatch read"

After hosting a server for a steam game, one client (same version as everybody else) gets instantly kicked after joining the server, because of:

Error: ReceivedRPC: ReceivePropertiesForRPC - Mismatch read.
Error: UActorChannel::ProcessBunch: Replicator.ReceivedBunch failed.

I couldnt really find usefull information for these errors, anyone got a clue what these could mean?
