Wifi scanning, no list appearing after having entered incorrect wifi passphrase

[ErwinCraps]

Hi
After updating the fifth M5Stick to a new wifi, I accidently entered a wrong passphrase.
As expected the stick tries to connect to the wifi but fails.
After this it mentions to connect to it's own wifi and visit the site 192.168.4.1.
Getting onto that site I pasted the correct password.
But I'm not able to save this because the wifi says "Scanning wifi".
Unfortnatly it keeps saying that, I waited about 10 minutes, no wifi networks are appearing in the list and I'm not able to save the correct password.
I will clearing the whole stick now to bypass this.
