Description

Opening any files in folders (attached) cause editor to crash.

Crash Reporter:

[Link Removed]

Frequency: 10/10

In user's project (available if needed), opening the project immediately crashes editor unless the attached folders are removed from the project first. If the assets are added back into the project while editor is open it will remain open until one of the blueprints is opened, which causes the editor to immediately crash.

Steps to Reproduce

1. Download attached .zip and unzip files
2. Add folders to any project
3. Open project with folders added
4. Attempt to open FPS_Character in \player\ folder
