Fortnite has to be started 100 times?

I always have to start Fortnite about 10 to 20 times before it finally works. When I start it, it always loads up to about 95%, then nothing happens for 1 minute and then the game crashes. Reinstalling brings nothing, have already tried it 6 times, on HDD, as synonymous to SSD

Could you give us some more info about your PC?

Ryzen 5 1600, GTX 1060 6gb and 8gb ddr4 RAM
