Thank you Larian_JB. Publishing is magically working again for me this morning thankfully. Typically I was opening it from my desktop but through a Steam-generated link (steam://rungameid/664400) but I'll change that up per your suggestion. Opening Steam Overlay seems buggy (the editor froze for me) but it did finally open as I quit the app. Good to know that the connection is on startup.
Thanks!
