spawn projectile won replicate from client. ue5.4

hey iv been trying to do some replication on the first-person template and everything works but the projectile. it doesn’t seem to wanna spawn it from client side no matter what i do. if i do it like most tutorials it just either crashes the client and it separates from the server. or it just crashes both my windows.

idk if its cuz its in a different blueprint than the actual character and don’t know what it should reference when calling in the shoot button.
i tried multicasting to server and server fires but same result of crashes. but it seams to work on server side


this is how it looks now without any replication only the setting turned on in the projectile. witch works for the server. but the client can shoot but it doesn’t show up on the server at all. only the server shots can be seen by client
