UE4.8.2 crashing while inserting more than 1 file(PNG) when source control svn ON

Dear ,

  1. correct, all of the InitD3DDevice are new PNGs (same pixel 512by512)
    1. I switched SVN to on
    1. inserted 2 PNGs (2x)
    1. inserted 4 PNGs
    1. tried to insert 8 PNGs

do you need the build of a new project? I will start and build and give a link to it.
give me a day to do so.

Many thanks.

Best,

Tigger
