Hello,
When placing assets in world the system often crash’s and I am attaching the file please is there any solution for it help melink text
That would be a video card related issue, have you tried updating your graphics card drivers, if you have and that did not work you could possibly try rolling the drivers back.
There is another person with the same problem here and will link you it to see if it can help at all: https://answers.unrealengine.com/questions/530765/error-0x887a0006-hung-when-editing-materials-leadi.html
