Roblox is currently crashing on start up for me as of tonight’s client update.
Based on posts in the Help forum, I don’t think I’m the only one having this issue.
My specs:
OS: Windows 10 Pro
CPU: Intel Core i5-4670K (3.4 GHz)
GPU: NVIDIA GeForce GTX 980 Ti
RAM: 16 GBs
From the looks of things, the crash happens just after the game finishes loading and is about to spawn your character
