Products not completely imported

Hi

I have tried to import a few products and amy of them are not imported completely. I waited more than half an hour and there are missing variations, pictures and video. One example is trying to import this product from Aliexpress

https://www.aliexpress.com/item/1005006319301350.html

This is just one example but I have found more. Products without many variations and without video seem to do better.

Also while importing a product I see a message saying “There still images in the queue but background process is not running” How to improve this the images seem to take to long to download.
