- New Windows PC experiences slow first launch of Unreal Engine game, taking nearly five minutes.
- Identified issue: Smart App Control, a default security feature in Windows, was causing the delay.
- Debugging steps included checking .dll loading times, profiling, and attempting to pre-load libraries.
- Workaround involved spawning multiple processes to load .dll files, reducing time to under a minute.
- Final solution: Disabling Smart App Control in Windows Settings resolved the issue completely.
