I'm very sorry to hear you all are having these issues with crashes! Please let me know if closing Uplay entirely, installing the latest version, running the program as administrator, and then verifying Roller Champions in Uplay helps to resolve these crashes.
Is anyone getting any form of error code?
Thanks for helping. Unfortunately, that entire sequence was completed and the game still crashes. I'm getting Exception Code: c0000005 where the Fault Module Name is described as UnityPlayer.dll and Fault Module Version is 2018.3.9.32286 which is the same as the Application Version value. The Problem Event Name is listed as APPCRASH. Hope it helps any.
