Hi @jtdaling, Not sure I can be of much help but at least I can welcome you to the forum with this reply! 
I updated my OP3T a few days ago (see this post) to end up on the dev build previous to the one you are on.
I have just now taken an OTA update to the latest e-0.12-q-2020110883452 which installed itself seamlessly onto the phone. Camera and video are working fine.
I don’t know enough about firmware versions etc to help, but would that affect how a system app installs? Not sure. Others on the forum should be able to help.
If this is your first time with eOS it might be worth trying a clean install again, but of the penultimate build: 20201105. This way you could then test the OTA update process into the bargain.
