One thing which is going on is that the meta data for your uploads folder is unhappy. Somewhere in the file is a character which isn't recognized by the utf8 format, I'd guess.

What happened right before this was:
2019-03-11 14:35:50,266 - octoprint.plugins.SlicerSettingsParser - INFO - Analyzing file: nozzle-fan-45deg_jp.gcode
It was trying to analyze a file you had uploaded. But then again, it was throwing that same error over and over before this, to be honest. Somewhere along the line this file has either become corrupt or something has written unicode data to it, perhaps. If you have added any plugins which analyze files, then they would be suspect to causing the problem.
If it were me, I think I'd run rm ~/.octoprint/uploads/.metadata.json and restart OctoPrint, letting it attempt to analyze all your files again.
Given that you have so many plugins, it would be difficult to guess which one might cause such a problem.

Fix your meta data then try running in Safe Mode to see if it is happier.
