Yes, I had this same problem. I found a config file in SteamLibrary\steamapps\common\Wolcen\system.cfg
In it there's lines after 'Local spec settings' where you can input your own resolution and change between fullscreen/windowed and remove '--' from the start of the lines so that
-- r_width=1920
-- r_height=1080
becomes
r_width=1920
r_height=1080
"
This allow you to make the resolutions settings to reappear
