So when i try and package my project i get multiple error messages that seem to point to my source file.

I checked my source file and I can see the error however i have no idea as to how to fix it (i dont know code, i made everything in blueprints)

Probably the “.” in your Class Name. Change it to a “_” instead aswell as your filename

Changing the name to something with no “.” fixed it. Thanks!

Just had this problem - my project name had 2 parts separated with “_” sign.

Error in Log told me that { is expected right after _ sign, so I’ve changed project name and it worked. I guess it is best just not to use any special characters as Unreal Engine project name.
(doesn’t apply to folder structure, just to the .uproject file name)

On my side I just had to delete the UE4Rules.pdb in C:\Program Files\Epic Games\UE_4.26\Engine\Intermediate\Build\BuildRules and run the packaging again.

thank you, working for me in 2023
