UE5.3.2 Crashes when using Steam Subsystem

Hi everyone!

Recently I have been working on a Project using UE5.3.2 and was implementing the Steam Online Subsystem, after enabling its features as described by Epic and some YT Tutorial (where obviously it worked just fine) and running as Standalone (cuz otherwise Steam isn’t gonna be initialized) the game instantly crashes, this doesn’t happen if you run the game within the Editor or in new Window (but not standalone)

I was trying different things since UE has sometimes its weird random crashes but nothing really helped, then I created a new Project and enabled everything there and guess what - it still crashes…

So I switched UE Version to well… 4.27 because that’s the only one I had and it caused most assets to be unusable but interestingly enough the Steam Subsystem worked!

I installed the newest UE5.5.1 and it works just fine
It seems that (at least) UE5.3.2 has some weird issue with the Steam Subsystem

I wrote this post for those who are stuck with the same issue, I tried everything I found on the internet, as well asked the good old GPT and nothing really fixed it, below the full log I get from Epic and a generated file, I hope it helps :slight_smile:

PS. it is related to the VtuneApi.dll and aqProf.dll, maybe that will hint someone

Fatal error!

Try the fixes in this thread

I would try this post first

I saw these Threads and tried things written there and unfortunately no success, right now I am migrating my Project to UE5.5.1 as it works just fine :wink:
