Raspberry Pi configuration is not opening while connected using windows remote desktop connection or VNC. I'm trying to open it from the main menu. It's opening if I connect RPI to a monitor.
If you're using tightvncserver this might help you.
I had VNC enabled in the RPI Configuration (uses realvnc) and installed tightvncserver after that on the RPI. Before that installation it told me that it will remove realvnc. So I guess RPI Configuration got confused with VNC enabled while realvnc had been removed.
Simply removing tightvncserver from the RPI, setting VNC to disable, and installing tightvncserver again did the trick for me. I probably just could have disabled the realvnc in the RPI configuration via the terminal
sudo raspi-config > Interfacing Options > P3 VNC > No (to disable realvnc server)
Or maybe you overruled another setting in the RPI Configuration.
Hope that helps
