EXCEPTION_ACCESS_VIOLATION reading address 0xffffffff

My project since 4.15.3 can’t be build because of this (this test in 4.16).
I found similar bugs in answerhub - but one with Mac, and one with coding.
Today I removed all data what was left from my attempt to include C++, so I believe I finally have only BP project.
Game itself runs without crashes, a month ago (since then almost no changes in blueprints) I was able to build shipping game.
I don’t know is it some old bug that finally showed up after update or new engine bug, or something else.
I am fighting this but in rather blind way trying various approach - so I am wasting time? should I just wait for next patch? maybe is this unrelated to engine (windows 10? drivers? Visual Studio? svn?)?.
