.net core 3.1 The TCP server received an exception byte stream

I developed a server APP with.net Core 3.1, which was compiled in Window7 and directly put into Linux platform to run. SocketAsyncEventArgs was used to handle network concurrency, but after the server ran for some time, the server received an abnormal byte stream.The complete byte stream is {0,0,0,164,255,83,77,66,114,0,0,0,0,8,1,64,0,0,0,0,0,0,0,0,0,0,0,0,0,0,64,6,0,0,1,0,0,129,0,2,80,67,32,78,69,84,87,79,82,75,32,80,82,79,71,82,65,77,32,49,46,48,0,2,77,73,67,82,79,83,79,70,84,32, 78,69,84,87,79,82,75,83,32,49,46,48,51,0,2,77,73,67,82,79,83,79,70,84,32,78,69,84,87,79,82,75,83,32,51,46,48,0,2,76,65,78,77,65,78,49,46,48,0,2,76,77,49,46,50,88,48,48,50,0,2,83,97,109,98,97,0,2,78,84,32,76,65,78,77,65,78,32,49,46,48,0,2,78,84,32,76,77,32,48,46,49,50,0}, I tried to use ASCII parse it, the result is {\0\0\0??SMBr\0\0\0\0\b\u0001@\0\0\0\0\0\0\0\0\0\0\0\0\0\0@\u0006\0\0\u0001\0\0?\0\u0002PC NETWORK PROGRAM 1.0\0\u0002MICROSOFT NETWORKS 1.03\0\u0002MICROSOFT NETWORKS 3.0\0\u0002LANMAN1.0\0\u0002LM1.2X002\0\u0002Samba\0\u0002NT LANMAN 1.0\0\u0002NT LM 0.12\0}, no idea what happened?

.Net core is not currently supported here on QnA. I'd try asking for help in dedicated forums here.
