Packaged game crashes on steam_api method call

I followed this guide, using editor version 4.24 and steam sdk 1.51

I have a button that opens a link in the steam overlay. It opens fine when I play from the editor in Standalone game mode.

But clicking the button in a packaged game (Win64) crashes it with a “Fatal error!”.
Also made a version where the button just calls SteamAPI_Init() - that’s enough to crash.

(The generated .dmp file throws “Unhandled exception at 0x00007FFED1A44F99 (KERNELBASE.dll) in UE4Minidump.dmp: 0xC06D007E: Module not found (parameters: 0x000000A58B17CBF0).”, but I’m not sure I’m using the .dmp file correctly, didn’t set-up symbols, just hit Debug button in Visual Studio)

Forgot to write, seems worth mentioning - steam_api64.dll isn’t present in the modules within the .dmp file (but it is packaged into /Engine/Binaries/ThirdParty/Steamworks/Steamv151/Win64)…

Placing steam_api64.dll in System32 folder solves the crash.

Why isn’t the game using the very same .dll that’s in Engine\Binaries\ThirdParty\Steamworks\Steamv151?..

Edit: Changing the binary folder name to Steamv146, and it works… I did everything the guides said, no clue why the packaged game is still looking for v146… w/e…
