Hi Kyle - what do your PC specs look like? (Minimum requirements).
I would also highly suggest contacting support for help as they are much better equipped to help you troubleshoot the problem.
(Also moving this thread into community support)
Had this happen last night in a dominion pvp. I'm on ps4 pro. Game kept dropping frames every couple minutes... about three or four times then froze up. After a few minutes the game closed and I got a playstation error message. I picked the option to send feedback with video.
Sorry I know this doesn't help you at all, but you're not alone. Hope the feedback finds its way to the problem solvers. (Ubi has those right?) Good luck.
