Steam API Disabled - Unreal Uses Wrong Version

Hi, I watched Unreal Engine’s official blueprint multiplayer tutorial and after video 11 I installed the latest version of steam API (1.44)

I did what documentation says except target.cs, build.cs codes and dlls but it didn’t work. Steam interface was visible but when I hosted a lobby and my other pc with a different steam account couldn’t join. It found, but couldn’t join.

After, I saw a warning when packing the game. Loading Steam API 1.39 (my version 1.44) and Steam API disabled.
After then I found other documentation in unreal wiki, added target.cs - build.cs and other dlls but nothing changed.

I can share any logs or other stuff if you want. Thanks for helping.

Apparently, Unreal is not supporting 1.44 as the release notes from unreal 4.22 states to support 1.39 as latest version.
I’ve been using 1.39 for about 6 weeks and I have no issues.
