Question by Manaflow · Jun 30, 2018 at 01:08 AM · erroreditor window

Assertion failed on expression: 'SUCCEEDED(hr)'

This error poped up earlier this week and Unity is currently unusable. Most of the windows are blank white. I have had this computer for 1 year and have had no issues up to this point. I get this error:

Assertion failed on expression: 'SUCCEEDED(hr)' (Filename: C:\buildslave\unity\build\Runtime/GfxDevice/d3d11/D3D11Window.cpp Line: 196)


This error appears at all times on all projects after selecting a project.


I have restarted Unity, restarted my PC, reinstalled Unity 1.1f1. Reinstalled the latest ver of Unity 2018. Ran dskchk, updated all my gfx drivers, made sure windows was up to date, and returned to a previous restore point. And finally I just reinstalled the OS (first thing I did was install Unity) and nothing has worked.


Windows 10 Home. Laptop. Inter(R) Core(TM) i7-7700HQ CPU @ 2.80Ghz, 2801 Mhz, 4 Core Acer - Aspire VX5-591G
