[X2Go-User] OT: key modifiers

I have a nasty problem not related to x2go. My desktop is Fedora 32/KDE (pretty sure doesn't matter if wayland or x11). Sometimes I need to edit a MS office document. I've been using vmware horizon to connect to my work, and fire up powerpoint. After using this, (and after closing down horizon), I find all my modifier keys are gone, ALT, CTRL no longer do anything. I don't know how to recover without logoff/logon. As you can imagine, this is not really acceptable. Anyone know how to fix this?

Thanks, Neal
