Your logs show that you have 2 instances of Plex Media Server.exe running - one as a scheduled task / service and another probably started by default on login to windows (option to auto start on login)
So one instance of Plex Media Server started at this time (this was an auto start session)

Having 2 instance of Plex Media Server.exe running in parallel would lead to corruptions, database locks and indeterminate outcomes
Please make sure you do not have auto start on login enabled if you are running it also as service or scheduled task - there is already a service wrapper in use by many users - including myself - covered by this forum topic PMS as a service - General / Tips, Tricks & How-Tos - Plex Forum and I have a specific post there near the beginning covering your problem - PMS as a service - #4 by sa2000
Another user had same issue recently and I responded here PLEX can not find my hdhomerun connect duo - #22 by sa2000
