so yeah it just closes when i click render as and it even happens with older videos ive rendered in the past. when i first got vegas 15 it was just fine no problems whatsoever and all of a sudden this is happening and earlier it wouldnt let me open projects or import media without closing, i found a solution to that though but i cant seem to find a solution to this problem anywhere and any help would be greatly appreciated because ive really enjoyed using this program until now and love what i was able to do with it and itd be really disappointing to have to give up on it and get a new program and to have wasted my time and money.

its vegas pro 15.0 build 416

i have windows 10 version 1803 (OS Build 17134.885)

my graphics card is an Intel(R) HD Graphics 620
