Decryption failure error occurred when sending data: shadowsocks::relay::tcprelay::utils: copy bidirection ends with error: decrypt data failed

Linux server, Linux client (Windows client has no problem sending small amount of data, but this error will still appear when uploading more data)
The outbound data flow is purely problematic. I have been looking for the problem for a long time. Today, I opened the debug log and checked in verbose mode: tokio-runtime-worker ThreadId(02) shadowsocks::relay::tcprelay::utils: copy bidirection ends with error: decrypt data failed, a_to_b: Running(CopyBuffer { read_done: false, pos: 0, cap: 0, amt: 0, .. }), b_to_a: Running(CopyBuffer { read_done: false, pos: 173, cap: 173, amt: 173, .. })
It can receive data normally, but it only appears when sending data. I am not sure if it is a problem with my client operating system or some other reason.
