Accurate Play Solo is enabled by default for games and the option to toggle it is removed. There is no option to attach the debugger to the client because a wonderful follow-up thread stated that you can simultaneously debug the client and the server.
I believe that changing between debuggers is as simple as changing between the server and client view. That, or I believe they show up in the same windows and differentiate between client and server. You’ll have to play around with this some.
@EnqryptedAPI That relates to having the debugger enabled at all. Not related to what OP is asking.
