Crash when save the blueprint function variable that set the StringTable asset

Crash when save the blueprint function variable that set the StringTable asset

UDN
Description

This issue doesn't crash in 4.21. It is rewritten as GIsSavingPackage = true in UPackage::(Save() when Blueprint is saved, but it's rewritten as false in 4.21.

Workaround

Do not set the String Table in default value. 

 

Steps to Reproduce
  1. Create Actor Blueprint and StringTable assets.
  2. Open String Table and add any text sets.
  3. Open Actor Blueprint and adding new function.
  4. Add Text variable to inputs.
  5. Set the String Table in Default Value.
  6. Compile and save the blueprint.

Result:

 Crash the editor.

Expect:

 Not occur crash
