Welcome

Description of the problem

When I use vless with xtls-rprx-vision flow, I get panic on the server, and client get connection refused.

Version of sing-box

server ```console $ sing-box version Environment: go1.20.2 linux/amd64 Tags: with_quic,with_wireguard,with_acme,with_utls,with_reality_server,with_clash_api Revision: ce6d18634525e5c74cfb8d73c06d6de2dc35ad5f CGO: disabled ```
client ```console sing-box version v1.2-beta9 Environment: go1.20.2 linux/amd64 Tags: with_gvisor,with_quic,with_wireguard,with_utls,with_reality_server,with_clash_api Revision: 74dffdd85a115babd2f58f011bb73d035d524323 CGO: enabled ```
