That seems to indicate the WiFi credentials are not sticking.
So we might need to check the basics:
First, how long did you let the Photon flash fast green? Let it happen at least a minute! Don’t hit reset but watch what colors follow.
Is your WiFi a 2.4GHz only or 5GHz (or both)?
Are you using WEP or WPA/WPA2?
Can you try to open your network (no PWD) and try again?
Is your WiFi hidden (no SSID broadcast)? Try to broadcast.
Again: Do you hear the Windows device connected sound?
Does Windows say something about a device not being connected properly?
Can you try a (or some) different USB cables?
Can you try a different USB port (preferably USB 2.0 not 3.0)?
