Sonarr Not Working After Update (Mono conflict?)

Sonarr: v2.0.0.5228 (pretty sure; don’t know how to find this)
Mono: mono-core.x86_64 5.14.0.177-0.xamarin.1.epel7 :
OS: CentOS 7

Debug logs:
I don’t know how to get debug logs from Sonarr without the web interface. Sorry.

Description of issue:
Thank you for your help! I saw a notification in Plex that an update was available, so I ran

yum update -y

Once the install was done, Sonarr stopped working.

I did some noodling online for the evening and found that a common culprit are conflicts with mono versions. I attempted to roll back mono using this:

yum downgrade mono-core-5.12.0.233-0.xamarin.3.epel7.x86_64
(which is the version I had last had working, I think)

That didn’t work, balking at dependencies I think. So, I removed mono entirely, hoping to do a fresh install of the older version:

yum remove mono*
yum install mono-core-5.12.0.233-0.xamarin.3.epel7.x86_64

…but when I did this, it forced me to yum install mono-core-5.14.0.233-0.xamarin.3.epel7.x86_64.

When I check the status of the service, I get this output:

[root@localhost ~]# service sonarr status

Any thoughts? Thanks in advance for your patience.

As of this morning both sonarr and radarr fail to start on my computer they have been running for over a year without issue. I am running on windows

What do you get if you run mono --version?
What about /usr/bin/mono --version?
