Network Manager Crashes Shortly after Starting

Additional Note. I have the core dump but when I try to attach it it won't let me file the bug report.

I tried running network manager manually using:

sudo /usr/sbin/NetworkManager -d

It has two errors:

...
NetworkManager[5989]: nm_device_get_device_type: assertion 'NM_IS_DEVICE (self)' failed
...
NetworkManager[5989]: <warn> failed to enumerate oFono devices: GDBus.Error:org.freedesktop.DBus.Error.ServiceUnknown: The name org.ofono was not provided by any .service files

When I do an echo $? it gives me 139 which based on my research means it segfaulted. Again I have the .crash file from the normal run if needed.

I found a fairly jenky work around. If while NetworkManager is off or crashed I use the hardware key combo to turn off wifi it does so. Then NetworkManager will start up. However it will attempt to enable wifi itself. So the next move is while it's starting up right after NetworkManager has turned the wifi chip back on you need to utilize the key combo again to manually disable wifi.

Then if I wait for a bit I can turn on wifi via hardware chip and it will crash in about a minute with the following in the logs:

My first thought is that I might have a wireless chip that's unsupported. However that doesn't seem to be the case given I'm running a certified laptop. I'm still doing some investigation but now I seem to be able to get NetworkManager to "stay up". Even if now I can't connect to wifi.
