hi @Bil_game78 ,  
There was an article about picking out code and translating  
[Asset Validation Issues - Issues and Bug Reporting](https://forums.unrealengine.com/t/asset-validation-issues/817504/14)

So the extracted bits to paste in the Outline window is  
2RVTAOI30XZ1U9AMBH9WOK

ZOJTLKMXTMQ8IBA19KOWT0

This should show the Asset that is failing

Experience shows this is due to project in a prior version for example 29.60

This next command could cause more problems and on do it if you are comfortable

The way the fix this is delete the content of the store in Windows File explorer  
C:\Users%USERPROFILE%\AppData\Local\FortniteGame\Saved\PersistentDownloadDir

to completely rebuild UEFN stores will attempt to build the corrupted store  
READ THE WARNING and if you are not comfortable with advanced troubleshooting dont use this  
if you type something wrongly you could do severe damage always use copy/paste commands
