Can't connect to wifi with RP4. Connects to wifi router after input name and password, but both IP address and Status show "Not Connected. I tried changing the Wifi region from JP to GB&US but no change.

WiFi gave me a lot of Trouble, even on a Rapsberry Pi 3B+ with Recalbox 6.0.
So I connect the Raspberry with a LAN-Cable to my Router.
Advantage: If you want to put some new Games on your SD-Card this is faster than a WiFi-Connection.

You say Recalbox shows "No Connect".
Which WiFi-Connection did you use ? 2,4 Ghz or 5 Ghz ?
I would suggest to use the 2,4 Ghz WiFi because this works better (a last for me) than 5 Ghz.

Did you own a Windows-PC ?
Did the Recalbox shows up under "Network" ?
I'm not sure if this will work for you, but why not try this:

1. Connect your Raspberry Pi to your WLAN (or if you want with a Cable to your LAN)
2. On your Window-PC open the "Windows Explorer"
3. Search for "Network"
4. Click on "Network"
5. The Name of your Raspberry Pi (for example "Recalbox") should show up
6. Klick on the Name
7. It will show you a Folder named "Share"
8. Klick on "Share" and you will see some more folders

Did this work ?

Another thing you can try:
Can you access the Recalbox Manger through you Internet-Browser ?
Look here

Recalbox 6.0 on my Rasberry Pi 3B+ also shows the Message "Not Connect" but I can access it over the Windows-Explorer and my Internet-Browser.

I'm not sure, but somewhere on the Internet (maybe on this Board) I've read that this message only means you are not connected to the "Recalbox-Server" and because of this you can't make an Update of Recalbox over the Internet, but everything else should work fine and you can access Recalbox in the Ways I mentioned above.
