Description

Adding assets to a project on a drive that is full still creates the file at the desired location instead of in a temporary location and provides no information as to why the asset is failing to load. Cancelling this action results in the editor crashing with no callstack. Attempting to re-open the editor produces the callstack provided. This process eventually corrupts the asset(s) created.

Frequency: 5/5

Regression (no) issue (does) occur in 4.12.5

Additional Notes May be related to [Link Removed], which was fixed in 4.11

Steps to Reproduce
  1. Completely fill a harddrive or SSD, leaving just enough space for 1 project
  2. Open Editor (any project with starter content) and save that project to the drive.
  3. Duplicate static mesh assets in starter content folders
  4. Continue to do this until drive completely runs out of space

Results

Editor says "can't load asset" but provides no additional information. The assets are showing as loaded within the content browser. If cancel is pressed, editor crashes with no callstack. re-opening the project produces the callstack attached to this bug report.

Expected

Error appears stating that there is not enough memory to accommodate new assets. Assets do not appear loaded in content browser. Cancelling action does not crash the editor.
