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)
