Exclamation SecureCRT 7.2 throwing "Session closed" error with GSSAPI enabled servers

I just updated from SecureCRT 7.1 to 7.2. It appears that all of my sessions I have defined to connect to RHEL servers running Centrify-Express with the Centrify enabled OpenSSH are instantly dying on connect with
"Session closed" or "Session reset"

How can I fix this? I tried creating a new session to one of these servers and I continue to get the same error. I also tried disabling GSSAPI and still got the same error.

I am still able to login with putty with GSSAPI enabled to these servers. I'd rather be using SecureCRT.

Here is a trace from one of them with the target server name anonymized:
