You could try several things including, disabling MPO, making sure chipset drivers are up to date, fooling with graphics settings. I personally have never experienced a crash in World of Warcraft. That being said I haven't played since before Dragonflight.
You should also post your other specs, CPU, GPU Make and Model, RAM Configuration, Storage Configuration, OS version, and Motherboard Make and Model. This will help others who come across your thread understand more about your particular setup and possibly identify the issue.
