Steam API fatal errors on UE5 BP game packaging. Help? *Edit: SOLVED*

I made a game entirely in blueprints, just added Steam achievements (they appear in the editor and everything. Very happy!), etc., all’s going well. I’m ready to package this bad boy. However, now, since I added the Steam achievement support, I get hit with “2 fatal errors” during packaging time:


I don’t know how to remedy these. Based on my searching, people say this error crops up when the Steam SDK version you’re using is “too new.” My questions are: How do I know which version to get, and how do I acquire an older SDK version at all?

If anyone has tips on any of this to remedy the errors, let me know.

EDIT: Leaving this here in case anyone needs it. Fix is to IGNORE EPIC DOCUMENTATION. Do NOT grab the latest Steam SDK; just delete the Steam win64 content from your UE install, verify UE files, then follow this video: Steamworks SDK SPEEDRUN (Tutorial) For Unreal Engine 4 & 5 (OnlineSubsystem) (youtube.com)

Epic’s still on Steam SDK v153 and using the latest version, v158, borks things. Not that the documentation explains that in any clear way…
