I have a ExitCode=25 (Error_UnknownCookFailure)

ive been working on a game on version 16 and when i package it works fine.
i opened a copy of the same game unaltered on version 20 of unreal engine and i get this error:
ExitCode=25 (Error_UnknownCookFailure)
it weird because it worked on 16 but not on anything beyond 16 (17,18, an 20)

also i have no blue print errors that prevent me from simulation game play.

Please help, i don’t know what to do. attached is the loglink text
Id be willing to pay if i you help me fix this issue. Thanks!

Hi supermanny1, the following error is in your log : UATHelper: Packaging (Windows (64-bit)): LogInit: Display: LogNavigation: Error: [/Script/Engine.RecastNavMesh] found in the DefaultEngine.ini file. This class has been moved. Please rename that section to [/Script/NavigationSystem.RecastNavMesh] . Please do as the error says and it should be resolved. I hope this helps. Cheers,
