Random crashing and disconnects

I don’t understand why this keeps happening. The game will be running perfectly fine and out of the blue it would disconnect, despite having no lag or internet issues, or start to lag so bad to the point where it is unplayable. The last bit is most likely my internet’s fault but there was one similar issue i have been facing. I will get into a game, and overwatch will close with a pop up that says “Overwatch is having trouble rendering” and there goes 50 sr. I have last at least 150 sr to this issue and season 12 has just started. Please tell me how to fix this

Have you tried any troubleshooting at all?

Hey I apologize for the late reply but I uninstalled the game and reinstalled the game and it seemed to temporarily fix it and some other issues.
