On the topic of AMD GPUs - a temporary workaround:

Use “-dx11” launch option on Steam.

Note: This will affect graphical fidelity of the game, but should alleviate the main cause for the crash.

How to add the launch option:

  • Select Quarantine Zone in your Steam Library

  • Right click -> Select Properties

  • Go into “General” tab -> type in “-dx11” in Launch Options

  • Start the game
