Fatal Error: FMallocBinned2 Attempt to realloc an unrecognized block when exiting a packaged game that has the Bink Media plugin enabled

Fatal Error: FMallocBinned2 Attempt to realloc an unrecognized block when exiting a packaged game that has the Bink Media plugin enabled

Description

When exiting a packaged project with the Bink Media plugin enabled, a fatal error is shown. This does not occur in packaged projects without the Bink Media plugin enabled.

The Bink Media plugin does not exist in 4.26, so not a Regression.

Steps to Reproduce
  1. Create a new project
  2. Select Edit > Plugins
  3. Enable the Bink Media plugin
  4. Restart the editor
  5. Package the project
  6. Run the packaged executable
  7. Exit out of the executable

RESULT:

A fatal error message appears after closing the packaged executable

EXPECTED:

There would be no fatal error shown when closing a packaged project with the Bink Media plugin enabled
