If it doesn't happen in Safe Mode, then it's likely that it's either something that you've added to the system, or a corruption of some sort of something that loads in normal mode but not in Safe Mode.
Easiest way for Safe Mode in W10 is to run MSCONFIG and select "Safe Boot" under the "Boot" tab.
Then reboot and it'll go into Safe Mode.
Or, you can try a Clean Boot (similar to Safe Mode - but you remain in normal mode): http://www.thewindowsclub.com/what-is-clean-boot-state-in-windows
The point here is if it's not present in a Clean Boot, then it's something that you disabled (in order to make Clean Boot work).
Then it's just a matter of re-enabling stuff a bit at a time until you find the thing that's causing the problem.
Another option (as this is an explorer.exe problem) is to use this free tool: http://www.nirsoft.net/utils/shexview.html
Disable all the non-Microsoft extensions and reboot.
Then see if the problem still exists.
If not, then it's one of the extensions that you disabled - so go through them a few at a time until you find the one that's causing the problem.
