HI @SubtoC4CTUS ,

In the log is the line

```auto
Error: ProjectSizeRequest: : CancelFlow for f45e4138-44ec-97f3-9c76-3590108e41c5 - Content (re)cook error errors. com. epicgames. cookplugin. assetvalidationerror.

```

assetvalidationerror = asset validation error

Therefore use the  
[Validation and Fix-Up Tool | Unreal Editor for Fortnite Documentation | Epic Developer Community](https://dev.epicgames.com/documentation/en-us/uefn/validation-and-fix-up-tool-in-unreal-editor-for-fortnite)

Look for changed/failed assets in the logs

Also, look at this thread to determine which asset is causing the problem  
[Asset Validation Issues - Issues and Bug Reporting / UEFN Validation](https://forums.unrealengine.com/t/asset-validation-issues/817504/14)

This is trying to find the project size

Try and use UEFN Memory calculator , before trying to log the session
