Freeze / Crash when running Trakt or Artwork Downloader

Finally narrowed this down, ongoing issue with slowdown, then complete freezing/crashing I've had with LibreELEC v7 and v8.

Completely re-scraped my library as I thought that 10 year old nfos were causing issues, turns out it wasn't this.

Fresh install of V8.0.0 on 3x different machines (2x Atom330 and 1x I5 4460), with the same sources and settings, all of which end up slowing down, then freezing completely when running either Trakt or Artwork Downloader. (more frequently with Trakt) - No response to SSH login etc

If I don't run either addon, everything seems stable, multiple hours of viewing and navigating the GUI.

Log below of most recent instance of a lock-up this morning (no crash log). Image of the GUI as it stopped responding.

Just re-created by running Trakt again but with extendedinfoscript disabled (after seeing an error with that in the previous log), same thing, hung again.

Hung again whilst running a Trakt sync, this time with debug enabled within Trakt itself also:

Still happening and reproduced on completely different hardware.

Either Kodi is causing Trakt to timeout or Trakt is timing out and causing Kodi to become slow and unresponsive.

I can still SSH in but this takes an age (screenshot below of trying to reboot via SSH)
