I'm a beginner of ue5, and I dont know how to fix this problem with publishing on steamworks SDK.

I definitely will!

I have one last issue, when i hit package on the package tool it says

PackagePushSteamTool: Warning: LogCook: Warning: Multiple packages found for map levelth3sh4dygr3y; it will not be added. Specify the full LongPackageName. Packages found:
PackagePushSteamTool: /Game/levels/levelth3sh4dygr3y/levelth3sh4dygr3y
PackagePushSteamTool: /Game/levels/thehub/triggers/levelth3sh4dygr3y

“levelth3sh4dygr3y” is a level in my game and it shows this warning for every map in my game, i figured it wasn’t a big deal but i tested the game and whenever i hit the trigger in “thehub”, it just took me back to the main menu.

All i have to do is fix that, and it will be published!
