Hello Shinee,
Please note that necroposting is against the forum rules. If you see a very old post that mentions the same problem you are having, create a new thread where you may refer to the old post. I have now locked the other old thread you bumped.
With this said I checked your diagnostic files and first seems you are using Bootcamp to run the game through a Mac system which is not supported and may give issues that we cannot completely troubleshoot.
Keep in mind this error also happens when the graphic card is not receiving sufficient power. Generally, this seems to be caused by, Insufficient PSU (power supply unit), Failing PSU or improperly seated GPU.
- Check to make sure the PSU has enough wattage to power the hardware in the PC, especially when the GPU is under load.
- Make sure the GPU is properly seated.
- A local computer tech can test the PSU to see if it is failing.
Try also to reset the Overwatch settings as some setting maybe incompatible with some graphics cards or monitors.
This type of crash can be also caused by overclocking, overheating, software conflict and corrupted or missing Windows system files. So try the steps here.
