Constant yellow light with error code 90.

I first stuck the sad card in but it said no sd chip.
I then upgraded the firmware and still the sad card doesn’t work. I removed the sad card and now get error code 90. I’ve rebooted the camera numerous times.
I deleted the Wyze app and redownloaded it from the App Store.
When I ran the app to setup the camera, the name that I had given it in the old app was still there.
And it still can’t connect.
It is 2 feet from the router.
