Engine Error Unknown File

Heya @S4ndgreen 

It's possible that some files from the game get corrupted from time to time, resulting in a crash you're seeing here.

To make sure this doesn't happen again, you'll need to delete the file in question and repair the game files via the game launcher you're using.

Let's start with deleting this file in question:

You'll need to navigate to the main directory of Apex, you can get there by following these guides depending on what platform you're using:

Steam

1. Go to your library and right click Apex Legends
2. Click on "properties"
3. Go to "installed files"
4. Click on "Browse"

EA App

1. Go to your library and click on Apex Legends
2. Click on the "Manage" button
3. Click on "View Properties"

Now that you're in the main directory, we'll have to move to the specific directory that this file is located in.

Let's follow these steps to get to this specific file and delete it:

1. Go to the materials folder
2. Go to the correction folder
3. Use the search function in the top right to search for "ability_hunt_mode" (Without the quotation marks)
4. Then once it finds the file, right click on it and press delete

Now you've successfully deleted the file, from this point we'll need to make sure the game will redownload this file so your game will work properly.
