This bug was fixed for RTX cards in an Nvidia driver update last year. If you are using the latest Nvidia drivers you no longer need to rename Overwatch.exe or launch directly through the exe. We updated the known issues sticky at the top of this forum.
GeneralAngry does not have an RTX card as well. He/she has Intel(R) HD Graphics 630.
Rendering device lost has several different fixes, however there are only a limited number of “software” fixes available for this. The error can also be caused by hardware/power issues within the system, so if the steps in the linked article do not help you may need to contact a PC technician or the system manufacturer for further help.
