For me it looks like you’ve specified some source content to use the thetvdb.com scraper which uses a payment model, meanwhile. At the end of the active log you see http 403 errors accessing files on thetvdb.com which means you don’t have permissions to do that. Also see Scraper TheTVDB will be switching to a subscription based payment model
I suggest you change the content of your sources to use themoviedb scraper instead.
