adobe premiere pro cc2017 hangs for a while when import .psd file

Hi. I am using adobe premiere and adobe photoshop cc2017. I am facing a problem when I import the .psd file to the adobe premiere timeline, adobe premiere hangs for 15 to 20 seconds and then processes it accordingly. I tried different methods like "drag and drop directly to the premiere pro timeline" "import to the bin", or directly drag and drop to the bin but the problem still exists. this is a very annoying stage for me when I working in flow and suddenly it stops working for 20 seconds. please anyone help to solve this problem.
