Hello BoBRoK13,

If you would attach entire output log of a your failed build in a txt file format. Here is a link for locating your project logs.

> **[A new, community-hosted Unreal Engine Wiki](https://forums.unrealengine.com/t/a-new-community-hosted-unreal-engine-wiki/141494)**

> After over a year in maintenance mode, the official Unreal Engine Wiki is now permanently offline. These resources now live on a new community-run Unreal Engine Community Wiki — https://unrealcommunity.wiki/! You will be able to find content from...

I will take a closer look at your logs at that time.
