Why did my editor start up once without problem but now crashes?

The title explains why I am posting this.
Now before you say the laptop I have is not really suited for it just take note that it has windows 10 on it and I have optimised the hell out of it (Including disabling services and using registry hacks along with enabling the HPET timer, the laptop is pretty fast now)

My dell laptop managed to run unreal engine 4.8 completely fine for one day but then the next it crashes with this below in the log:

Just to update on this, I deleted and reinstalled 4.8, still the same error. I don’t know what’s happened.

Hi NeoReaper,

You called it. The first thing I’m going to say is that your laptop is way under spec. The second thing I’m going to say is that we currently do not support Win10.

Can you go ahead and uninstall 4.8 (and any other versions installed) and uninstall the launcher. Go to your program files folders and clear anything related to Unreal Engine and delete any projects in Documents/Unreal Projects. After that, reinstall from scratch and let me know if it still occurs.

PS - Can you paste your callstack into a txt file and attach it? Callstacks lose all formatting when pasted into the Answerhub comments.

Hey NeoReaper,

I’m marking this as answered due to inactivity. Please respond to reopen the issue.
