Can you test it without KCP enabled?

I did not enable KCP manually in my server(and i dont know how to disable it, i tried the method below but it does not work), the OS is ProxmoxVE-8.0.3(based on debian 11).

Maybe it's not relevant, just ignore it for now.

Is there a log before the fatal error? Were there any changes to the system, network, etc. before the crash?

It's my first time I've used frp in this server.
But as i mentioned in the issue body, i started another frpc instance, which is stable:

serverAddr = ""
serverPort = 7000

[auth]
method = "token"
token = ""

[[proxies]]
name = "ssh"
type = "tcp"
localIP = "127.0.0.1"
localPort = 22
remotePort = 2222

[[proxies]]
name = "pve"
type = "tcp"
localIP = "127.0.0.1"
localPort = 8006
remotePort = 8066

(both instances use the same frps)
