Im getting an error when packaging my project to Windows

Hey my name is Zach and I’m an amateur fourteen year old Unreal developer. I developed a game for a school market with my friends and people preordered it and will recieve it as soon as we can package it - But that’s the issue. I upgraded the 4.18 version of the project to 4.19.2 and I’m unable to package it to Windows-64 bit. Please help! I get errors and it says ‘packaging failed - Read output log for details’ yet I understand next to nothing of the errors. It says I need VS8.1 and I have the latest version and I have the Windows SDK development kit. Help me as soon as possible please!

Can you link the output log?

@HarryHighDef Sure here it is.
