[X2Go-User] freezing after update to fedora 37

Been using x2go for many fedora releases. After updating both client and server to fedora f37, I have a new problem. I've tried multiple desktops, including xfce and lxde, and have the same symptoms. After starting a session, it initially works fine. When I come back later to try to use it, it is frozen. So I have not disconnected from the session and reconnected. On the client side the screen was locked and then unlocked when I returned. The client did not suspend - it is running on A/C power.

The session is frozen and completely unresponsive to input. Disconnect/reconnect it's still frozen. Only terminate/new session will unfreeze it.

Any suggestions?

Thanks Neal
