My project crashes on opening

Hi,

I was working on Unreal on some inventory system. I managed to make it functionnal. Everything worked fine. I saved my project, and then I had to go (for like, 10 mins). When I came back, Unreal has crashed, and since, I can’t open my project ! It keeps crashing aroung 93% on opening…

I worked all the day on that Inventory system and I would go crazy if I’ve lost everything I made today…

Here’s my log file :

I see this “[2018.08.24-00.34.09:418] 0]LogLinker: Error: Bad name index -1/402” But I have no idea of what it is…

In case if it helps :
LoginId:2b8b07aa46c9a73ead9cdcbbc00a79a3
EpicAccountId:3b38f417fd9148b5a0f61fedd2bd3d32

I would really appreciate any help…

Thanks a lot
