Sims 4 flashes black and white then crashes

Wombat_Justice​  Don't worry about the late reply, it happens.

The initialization error is typically antivirus-related, but since you're not always seeing it, let's put that aside for now.  Instead, try one of these workarounds:

HP gaming laptops often show a white screen at startup, and there are a few workarounds for this particular issue:

• HELP! The Sims 4 crashes during launch or in the main menu | EA Forums - 12048779
• Game won’t launch | EA Forums - 4992631
• Managed to fix my problem where it crashes during launch after update | EA Forums - 4998584
• Disable the Intel iGPU
• Put the laptop in night mode before trying to play

None of these works for everyone, but something almost always does, so keep trying the workarounds until you find one that lets you play.  You can try them in any order.
