Thanks for the server logs. For downloads issues, it is crucial that diagnostics are provided from both sides - the plex app doing the download and the plex media server
I can see transcodes for downloads starting for Toy Story.mkv
and Toy Story 2.mkv
at 21:00 on 18th Feb but the transcode is beings topped by the Plex client app a few seconds later. Would need the corresponding logs for this period from the Plex app
Observation: Seeing a lot of relaunches of Plex Media Server - a bit strange relaunching every few minutes. - was it to do with the network issue I mention below?

I see you are running PMS as service or scheduled task - there is PMS As A Service wrapper provided by a user here which you could consider PMS as a service - General Discussions / Tips, Tricks & How-Tos - Plex Forum
Another observation: Some transient network issues
DNS / Internet down at these times - repeated errors at these times
