I'm guessing you only had one entry and still had WIFI_AP_ENABLE
on,
The output in console is not very clear when configured like that' I'll make a small fix so that scan is suppressed and a proper 'AP Mode On' message emitted.
I've also worked on the commenting and layout of the list definition. This is still a work in progress so apologies for all the confusion.

third try and success.
now the same firmware and modul is running on usb-port on same pc as before,
and also on powersupply..

Scanning local Wifi Networks
Brownout detector was triggered
That's your problem, right there.
When the WiFi scan starts themodule is drawing more power and the voltage dips too low, aka a 'brownout', it is a hatrdware failure that cannot be fixed in code.
Doing a network scan is a high power operation, so it's entirely possible that the code worked before, but starts to fail now, and the following 'camera sensor failure' is a follow-on from that, it has browned out too.
Doublecheck your wiring.. thin long wires can cause the voltage to drop as the unit draws more power, as can weak power supplies and dodgy solder/crimp connections. If it is any comfort, you are not alone. I had to beef up the wiring for one of my cams.
Another thing I have seen others doing is to add a big(ish) electrolytic capacitor on the board between the 0 and 5v lines to smooth out spikes/dips. This seems to help with interference on the video too by keeping the camera sensors voltage constant. Use a 220/470uF electrolytic and get the polarity right ;-)

thx for the infomation. i guess is pushing me in the right direction.
i had problems with the left one as shown on picture
(on PC-usb port and on some powerfull usb-hub too - i will change this now again),
and i will also try if the other module works better on only 2 wires 5V...
after that, i will try a complete other powersource --
and not questioning the firmware for sometime 😉 , or until release 👍 😉 ...
thx
sidenote: the leftmodule runs with the same cables fine with firmware Oct 6 2020 @ 14:50:14
on my usual usb-ports, where the same module and cable on the same usb-ports but with the new firmware v3beta3 shows this errors..

I think that this is because the WiFi scan is very active and uses a lot more power than the previous 'start and just listen' mode..
It's quite common, I found a lot of similar issues, eg: espressif/arduino-esp32#863
PS: I've also had cheap dupont hook up wires go bad on me, sometimes there is not a lot of metal inside them..

i flashed it again on the usb-port on my PC (where if failed before),
but got luck this time... ( i will keep tryiing..)
changing for wifi-credentials on myconfig.h for my local wifi
to a "struct" is little bit confusing...

Oops. Fat fingers.
Glad you got it working.
