Kodi scraping really slowly on Nvidia Shield Pro (2019)



Hi all.
I’m hoping that someone can help me.
I have the current version of Kodi (21.1) installed on my Nvidia Shield Pro (2019) version.
All is working perfectly including connecting to my home cinema amplifier etc.
All my media is stored on a Synology NAS drive and I can play all my media perfectly without issue.
I have set Kodi to automatically scan my NAS folders for any new media.
The issue I am having is that scraping appears to take forever, sometimes it takes about 15 mins for the scraping progress bar to even move to 1%, where it take take over 1hour to complete.
I only have this issue on the Nvidia Shield, and have Kodi installed on my Windows PC’s as well as generic branded Android TV units, also connected to the same NAS unit, where the scraping takes seconds to complete.
Please advise what may be causing this issue.
I have uploaded the Kodi log file onto the hastebin portal, and the link to it is below.

Many thanks in advance, and hope to hear from you soon.
