Back Office edit product page not loading sometimes

[RosiestFuture]

I am getting this console error very frequently whenever I try to edit a product.

The combinations won't load and, whenever I select an image to change the legends it won't load it, just a blank space.

Then if I refresh the page it would ask me to log in again and redirect me to the home back office page.
