Windows 10 WiFi - "the network security key isn't correct"

Hi Experts,

I've got one Windows 10 PC that will not accept the security key.
I click the little icon that makes the key visible, so I know it's the correct key.

It's been happily using the same key for months.

I have about 10 devices that are using the same key.

Regards,
Leigh

Is there MAC filtering applied?

Also, I would try to reset the network.
Settings -> Network and Internet -> Status -> Network Reset -> Reset

There's no MAC filtering.

I tried the network reset, but still the same error....

I would also update network adapter drivers.

Wow!, that got me connected!
Should re-enable all the other adapters now?

The WiFi network adapter driver was already up to date.

Thanks, Hello There.

"Should re-enable all the other adapters now?"
Turned out that all bar one were re-enabled by the network reset.
I re-enabled that remaining one and still connecting OK.
