• For BullGuard users: Select Settings → Main and uncheck Self protection.
  

If issues still persist:

• If you are using Razer Synapse, make sure to update to the latest driver.
  
• Perform a clean boot and only start up with the bare minimum programs: How to perform a clean boot in Windows
  
• If the game doesn't start and you have disabled ASLR on Windows, re-enable it.
