Blueprint File Not Found in Editor

Development Programming & Scripting Blueprint

After an unexpected shutdown of Unreal Engine, I reopened my project and found that a crucial Blueprint file is missing from the content browser, although it still exists in the Windows file explorer. I have already tried the following solutions:

  1. Deleted the Binaries, Intermediate, and Saved folders and rebuilt the project, but the Blueprint file still does not display.
  2. Used the “Fix Redirectors in Folder” option in the content browser, but I encountered errors in the output log:

This Blueprint file is very important to me. Any assistance would be greatly appreciated!

In this case, just get it from the backup. :upside_down_face: (sarcasm)

Before the crash, did you change the structures/enums used in this blueprint?
Make a backup of what you have (first).
Try renaming the blueprint/moving it to another folder/+ creating a blueprint with the same name in its place/move blueprint to another project.

I was editing the missing Blueprint file when the program crashed. Unfortunately, there is no backup file because I deleted the Saved folder to rebuild the project, and there is no version control implemented in this project. The only file I could find is the .uasset file of the missing Blueprint in my Windows file explorer.
