If you don't get a response here there is a ESP_NOW expert on the Micropython forum ... might be worth asking the question there as well.

Just looked at the EBYTE datasheet. 1W output, maybe try reducing the TX power. Have you got a SMA 50 Ohm termination you can try on the antenna connector? Is the ESP32 on a dev board? Might need a schematic showing your connections.

I would like to get the sensor values so that I can save them after taking
3 pictures. Go to lightsleep for a few minutes, wakeup and recall those
values. Then try to only take one snapshot, hopefully without the green
tint.

I tried following through:

First thing I would check is the amount of current drawn out of the 3V3 regulator by the GPS module and OLED display. Is the ESP32 on a dev board? You really need an oscilloscope to watch for voltage "dips" while things boot-up.

What happens if you leave the GPS module disconnected during boot-up?
