New session cannot be connected

version：windows1021H1 WindTerm 2.7.0

When I create a new session, I will be prompted to disconnect, but I can access the server normally by using ssh or other ssh tools with cmd. I turned on the log switch, but there is no log output. What else can I provide to help locate the problem

No source file, test, or entry point is identified. Start by reproducing the failed new session on Windows 10 21H1 with WindTerm 2.7.0, compare it with the working SSH command-line connection, and determine what diagnostic information can be collected; done requires a reproducible diagnosis or a confirmed fix.
