Thumbnails not opening and crashing Kodi/Libreelec

So I bit the bullet and bought a new Odroid C2 to replace an aging Acer Revo 3610
My current set up is running 15.2 Isengard with an old Kodibuntu OS. For whatever reason I have been unable to update Kodi on this install for a while.
I have set up Libreelec 8.01 on the Odroid and added sources as required. I then copied my existng 15.2 database files to the new Userdata folders. The library imports and the watched status etc all comes across fine.
The problem I am having relates to thumbnails loading (or not loading) and crashing the system causing a restart. Some times I can scroll through slowly and let the system either find or load a thumbnail but I eventually get to a movie and it will crash.
This is the log file, hopefully someone can make more sense of it than me
Log File
I was thinking I could delete the databases again and just do a fresh scrape on the new Odroid. That should get all new thumbnail details. If I then tried to copy the old MyVideos database file across do you think it would work and find the new thumbnails?
Its all a bit odd as I managed to do the same thing on a raspberry pi with Libreelec 8.01 and it worked fine.
