Endless loading screen and can't abort or restart this

I've been attempting to enter a map for over an hour now with no success. After logging in, I launched the map, entered the portal, and that's where everything stops—the game continuously displays the map loading screen with no progress. I've tried every troubleshooting step imaginable: rebooted my computer and router, switched login servers, closed the game for ten minutes, even changed from Vulkan to DirectX 12—but nothing resolves the issue. Each time I log back in, it persistently attempts to load that same problematic map.

Out of desperation, I tried logging in with a different character. I successfully entered my hideout and saw the portals standing there, ready to take me to that same map. Unfortunately, attempting to enter through this second character resulted in the exact same infinite loading screen.

Thankfully, I had a third character available, which allowed me to launch an entirely different map and break this frustrating cycle. But what would have happened if I didn't have that third character to fall back on?

Adding to the frustration, I had an Infection boss active on that map, and now I'm unable to clear the monsters and obtain the purified crystallized bosses. Please address this issue so that map activities don't disappear simply because I couldn't access the map. We've seen similar problems before with other Atlas activities—previously, an activity would simply count as a failure even when I couldn't enter the map at all.

This issue occurred yesterday, and my logs show these relevant entries:

```

After these entries, the infinite loading begins. This particular error regarding the missing EPK file appears to be the root cause of the problem.
