I tried sending all trains to depot to clear up any clogs and upon releasing them again they are lost again.

Your station layout allows trains to wait in unfortunate locations, and doesn't have a clear way in separate from the way out.
I notice you have individual orders for all your trains, instead of using shared orders. Using shared orders makes it much easier to manage your vehicles, and could let you change all of them at once. What I would suggest is also adding a waypoint on the route to Trendinghattan Woods.
Overall, I think your problem is that most of your track is bidirectional instead of unidirectional, and you have crossovers everywhere even places they aren't needed. It confuses the pathfinding.
You should also be careful about having stations shared between loading and unloading trains. You can end up with all the platforms taken up by loading trains, so unloading trains can never get in and unload, and so the loading trains will never get any cargo because the industry can never produce anything without raw material.

- This is a straight line with one track per direction, you don't need crossovers (they only cause problems)

- Changing the station to a Ro-Ro layout lets the trains pathfind better and avoids sharing tracks for ingoing and outgoing trains

You can open the console and type `set pf.yapf.max_search_nodes 20000` (double the default maximum), but you'll need to manually fix the trains that are stuck.
Basically, what jfs said
The best long-term cure is still to simplify your network so trains don't have so many choices all the time. Make dedicated tracks for each direction instead of both-direction tracks, and avoid crossovers on long stretches of tracks. Using waypoints can also help since the trains don't need to pathfind as far at a time.
