Issues with OpenSSH Server

[Sabarigirisan S]

Hi

We have been using OpenSSH server for our windows environment for quite
some time close to 4 years and starting Saturday, we noticed that there is
some sort of weirdness where the console is not getting returned after
completion of connection from the client.

With heavily automated infrastructure, the automation scripts are breaking
currently.

Even from the localhost, when we open the cygwin terminal type exit, it is
not closing the console

Tried reinstalling Cygwin but the install process hangs forever on
ca-certificate post installation.

Can someone tell what is wrong here,

Regards
Sabari
