Hello CoffeeHerald,
I’ll be happy to look into finding out what is causing this with you. When looking up your MachineId and EpicAccountId in our system, I don’t see any instances of this crash report submitted into our system. I do see an IsValid crash from 9/6/2016 but that’s all. Have you been hitting “Submit” on your crash reports?
What version of Perforce are you using? Have you tried setting up a new repository to see if that may fix the issue? Are you using any additional plugins with the engine that could possibly be interfering?
