Linker Errors LNK2001 & LNK2019 when packaging the project

I don’t know anything about or use C++ but I am getting this error after updating my project from UE4.27 to 5.2

Any idea what I can do to fix this?

My output log: LogUObjectHash: Compacting FUObjectHashTables data took 0.59msLogTurnkeySupp - Pastebin.com

Could this have something to do with it?

LogLauncherProfile: Unable to use promoted target - …/…/…/…/…/…/Users/Jackson/Documents/Unreal Projects/RRM4 5.2/Binaries/Win64/RRM4-Win64-Shipping.target does not exist.

Edit: Got it working: Unknown Package Error UE5.2
