Netgear router not working after Internet Modem changed to Arris TG4482A
I upgraded my internet in the last month or so, which came with an Arris TG4482A Modem/Gateway, and my R7000P keeps dropping out constantly and my Xbox One won't even connect anymore at all. Event lo...

A double nat happens when you cascade more than 1 router.

Fixes? There’s 3 options but only use 1.
1. Put the modem/gateway in modem only/pass through mode. This disables its routing functions.
2. Leave the modem/gateway in router mode but put the Netgears IP address into its DMZ. This forwards the data to the netgear. You can either leave the modem/gateway’s wireless enabled or disabled. Just make sure its using a different wifi channel to prevent interference
3. Put the Netgear into access point mode. This disables its routing functions. Wifi/ethernet still works but it does disable some features.

The Arris Gateway is in bridge mode, so shouldn't be a double-NAT situation (from my understanding from the article). I'm a Netgear Armor user, so that would make my subscription unusable by operating in AP mode (coincidentally, my Netgear Armor subscription has also become disabled). I do have an R7000 in AP mode that is running under the R7000P, but this has never been an issue. Both routers are updated to the latest firmware.

Shouldn't and isn't are two different things.
The people who make these things have habit of using different terminology and ways of going about things. For a start, "bridge mode" means different things with different devices. For modem/routers, I prefer the term "modem only".
Your cascade of hardware is looking increasingly complicated.
Arris TG4482A > R7000P > R7000
Is there any wifi SSID visible from the Arris TG4482A?

No SSID from the Arris. The R7000 in AP mode simply inherits all its settings from the R7000P. It was working fine until my ISP forced me to replace my modem with the Arris. Again, I'm having repeated critical errors in the event logs on the Arris which seems to be related to IPv6.
It wouldn't be the first ISP supplied device that didn't setup properly in passthrough/bridge/modem only mode.
Have you tried leaving the arris in router mode (disable its wifi) and putting the R7000P's ip address into its dmz?
OR even just the arris in router mode with both netgear in access point mode?
