Hi lovelies!

We’re encountering a fun little problem with trying to compile to the Nintendo Switch for the first time. When we compile it in debug game configuration, we get an Access Violation of Data crash after we launch the game  
Here’s the call stack of the crash

Anyone familiar with this issue? Are we doing something silly?

oh, here’s addititional info, we run UE 4.24.3, and the latest FMOD, which is 2.01.00. And we use SDK 9.3.1

Cheers,

Daniel

Are you getting any logging information before it crashes?  
Are the FMOD banks being included in the “Additional Non-Asset Directories to Package” or “Copy”?
