My NetworkManager has suddenly stopped working on my raspberry pi due to which I am unable to connect to it either via putty or http. Configuration: I run a Raspberry Pi 3B+ with Raspbian. It is also running hassio on docker. Everything was running smoothly and I have not make any changes to the Pi. I was only fiddling with my router trying to change some wifi settings and my Pi went incommunicado. When the pi boots up it gives the following error:
NetworkManager has failed to start
journalctl -xe gives the following error:

It retries a few times and then gives up. Can somebody help me troubleshoot this please. What else would be of value to see in the configs?
