**CRITICAL**- Can't launch UEFN session after v36.00 - verse code Validation Fails, pointing to sys/published outdated code

[BushyBrowse]

Actually I just found that this resolved my issue! 100%

Steps to resolve:

1. Close UEFN completely (Until it says ‘Launch’ in the Epic Games launcher again)
2. BACK UP YOUR PROJECT MANUALLY. URC + MANUAL BACKUP FILE.. PLEASE!!
3. Go to the file location of your ‘.uefnproject’ file
4. Open the .uefnproject file in VSCode
5. Add the scenegraph section exactly how it looks from this post:
   (Clarification: DO NOT REMOVE ANY TEXT, you’re just adding the section in the red square)

6. Next, go to your 'projectname/plugins/projectname/ folder
7. open the .uplugin file in VSCode
8. Add
   "EnableSceneGraph": false
