it is text file with some binary characters. you can run cat freeze | xxd to see what is inside
now ssh to the remote machine from the WSL ubuntu 18.04 terminal

This will freeze the terminal.
But if you type exit, you will exit the ssh session and things will start to work normally.

i usually run ssh service in WSL, and use XShell to connect to WSL.

It fails in WSL but not in XShell.

Did you try that in the new Windows Terminal?
In any case the upcoming Windows 10 version 2004 (build 19041) has a fix that perfectly fits your problem. #4495

But also, why would you cat binary files to your terminal?

Not intentionally doing it. When you cat a text file, it has few random non printable text, terminal hangs. It's really bad experience. All the other terminal programs handle it perfectly.
