Hello, thank you for the response!

I was not experiencing any lowered frame rate, the game would run flawlessly then suddenly freeze and the error dialogue would pop up. It's a new laptop so I can't really compare it to a prior state, but I did update my NVIDIA graphics driver and Windows 10 OS to their latest updates. I closed Skype, Discord, Spotify, Steam, Chrome, which are all the background apps I usually leave open, and added the client to my antivirus' exception list just in case that was interfering with the game.

I have not tried lowering the resolution or graphics settings while running Direct X 11 yet, but I did disable Direct X 11 mode and the game ran smoothly for a good 7 hours before it crashed once. Played another long session of 8 hours after and the game didn't crash at all. I'll try lowering the resolution and graphics settings with Direct X 11 on, but for now disabling it seems to work!
