Hi Awccd,

Thank you for submitting a bug report. I logged it as UE-42478 which you can track on the following link: Unreal Engine Issues. In order to be able to address this issue, please provide as many details about the bug as possible. Can you reproduce this with a certain asset migrated to a blank project? If so, would you be willing to share those assets so that we can reproduce the bug on our end.

Please respond with as much info as possible.

Thank you,

-.

I used to have the same problem and the engine keeps crashing for every movement I make , but I figured that this issue happened when I have updated my Nividia drivers so I have rolled back to the old drivers and the problem was solved
