This isnt work for ive tried it a couple of time and its not working. i dont rly know what to do
Hi @ duck slayer,
I think my solution was, after installing the debugging tools, to migrate the whole project to a new one.
Apparently when you install the debugging stuff, it doesn’t affect the already existing projects but only the ones you create from that moment on… I think. Maybe try this and let me know 
OMFG this fix worked for me, if it is a Fortnite error then go into device management and check your display adapters. If you have multiple that is something like 1 Nvidia and 1 intel integrated graphics ( HD …) then disable the integrated graphics. This might mess up other games tho. Do this with caution as I wont be responsible for anything that may have broken.
1- Good first to open the laucher and click the configuration symbol in the right corner of laucher,
2- And click Enable debug logging…
3- Then click Check
4- After checking the game will automatically install data that lack and who are giving error
- I hope I have helped
