UE4 randomly crashing a lot - Losing a lot of stuff - Return some data loss and error

Hey guys I looked at the forum but did not found the answer.

I’m using 4.16.3 UE4 and having a lot of bugs all day long. Sometimes I can get data back but sometimes it corrupt my project, and for exemple destroy my HUD images (all blank) and have to re make everthing, wich someone means hours of work lost.

So I don’t know, I have the 4.17.1 but I prefer the 4.16.3 for using market assets. But I think thats not relient to my problems, right ?

My last bug was 5 min ago, i was in a personnage Blend Space, looking animation (click on them and watch) then doing the Blend Space then suddlenly everything shut (no freeze etc, just a simple instant shut of UE4 and when press Send and Open 1) ive lost some works because i dont save every 2 minutes, and I’ve got some corrupt things.

I use only Fuse CC, Mixamo and UE4 (my characters and animations for the Blend Space are from Mixamo)

So I dont know, but it’s sooooo boring. I know you have a lot of stuff, and I dont disclaim UE4 at all but if we can find a way to fix those constants bugs, it may be cool (not only for me)
