Whenever I try launching the editor it crashes

Hello, I was running UE4 just fine until yesterday afternoon when it suddenly stopped working. The only thing I did differently was download the Blueprint Office pack.

Here are my relevant system specs:
i5-3570K @ 3.4 GHz
16 GB RAM
AMD Radeon HD 7900 Series

Here’s a picture of the crash for reference:

I’ve tried doing everything that people have recommended on here but to no avail. I’ve uninstalled and reinstalled a thousand times, deleted all relevant data in my User Data folders, checked my registry to make sure everything is gone and then installed.

I also have an SSD and a regular Hard drive and I’ve tried having UE4 installed on both but that hasn’t seemed to affect anything.

Here’s my callstack from the crash last night:
Assertion failed: InPos<=Bytes.Num() [File:D:\BuildFarm\buildmachine_++depot+UE4-Releases+4.0\Engine\Source\Runtime\Core\Public\Serialization\Archive.h] [Line: 161]

I tried copying the callstack from this morning but it kept copying the “We apologize for the inconvenience text instead.” I would assume the error is the same except that instead of the directory being D:\Tools\Unreal Engine\ it would be C:\Program Files\Unreal Engine

I hope one of you can help me because I really wanna get back into UE4 development ASAP.

Thank you for your time.

Hello,

Thank you for the information you have provided. Could you please post you log files? You can find them here:- C:\Users\ AppData\Local\UnrealEngineLauncher\Saved\Logs

That will help us further investigate the issue.

Cheers!

Hey, thanks for getting back to me.

At this time I no longer have my logs as I wound up completely formatting my computer to address this problem as well as other seemingly unrelated problems I was having. I ended up switching over to Windows 8 and it seems be working fine now.

Thanks again for reaching out though.
Cheers.
