Given the new v.8 version problem with synchronisation (port is closed) I've tried to "connects through SOCKS5 proxy" in Options>Network. This leaves me now locked out  ans each time I start the app it gives me the following error "unsupported argument -sock found. Setting SOCKS version isn't possible anymore, only SOCKS5 proxies are supported"  and then the app closed. How do I revert not using the SOCKS5 setting?   Error screenshot

Seems you already fixed the error in another thread, adding [Solved] to title.
