[BUG REPORT] UE5 Migration - Critical Issues: UI Scaling, Window Mode & Crashes

Dear Devs / Community,

The new client introduced massive and graphics redesign. In this post, as soon as I notice several issues that are preventing a proper gaming experience. Here are my findings:

---

🖥️ 1. UI/Interface completely broken in Windowed Mode (Dual Box)

When attempting to play in windowed mode (essential for dual boxing), the entire interface breaks:

• Skill bars become misplaced or disappear entirely
• Target window floats out of position
• HP/MP/CP bars lose their layout
• After 10-15 minutes of manual adjustments, it's possible to reach something barely functional — but only if you accept microscopic icons completely disproportionate to the screen

This issue is clearly visible in the screenshots attached. The in-game Options menu offers UI Scale settings, but they do not properly fix the layout in windowed mode.

This is especially problematic for 4K monitor users.

💥 2. Fatal Crash every 5-15 minutes

After the UE5 migration, the client crashes with:

"The UE-LU4 Game has crashed and will close — Fatal error!"

This forces players to:

1. Restart the client
2. Log in again
3. Repeat the entire 10-15 minute UI adjustment process from scratch

This makes the game practically unplayable.

🔇 3. Audio — Only music, buffs and drop sounds work

Most of the game's audio is completely silent after the UE5 update. Only the following sounds are audible:

• Background music
• Buff activation sounds
• Item drop sounds

All other audio (combat sounds, skill effects, NPC voices, footsteps, etc.) are completely missing.

📋 System Info

• Monitor: Odyssey G9 57"  / GPU RTX 5090
  Mode: Windowed (Dual Box setup)
• Engine: UE5 (post-migration client)

These are not minor inconveniences — they are game-breaking issues that make normal gameplay impossible. Please prioritize a hotfix.
