Hello,
Today I packaged a heavy game and the “second” time that I wanted to run it it crashed. (D3D error)
My only option was to restart my PC. Then again, I could only open it once till I restarted the machine again.
Then I realized if I exit epic games on the “system tray” I can run my game for as many times as I want without having to restart my computer. cheers.
Hope it helps you too.
