In the realms of guess work now:

Main Fixes to Try

1. Input Device Conflicts (most common solution):
   • Disable Bluetooth completely (Windows Settings → Bluetooth & devices).
   • Open Device Manager (right-click Start → Device Manager).
     • Under Keyboards, remove the duplicate entries (uninstall all but one), then restart your PC.
     • Also check Bluetooth, Human Interface Devices, and Sound, video and game controllers for extras and disable them.
   • Wireless devices or hidden pairings often cause this.
2. Launch in Windowed Mode:
   • Locate the main game .exe in your Starmaker Story folder.
   • Right-click → Create shortcut.
   • Right-click the shortcut → Properties → Target field.
   • Add at the end (after the closing quote): -screen-fullscreen 0
   • Try launching with this shortcut. You can also experiment with -screen-width 1920 -screen-height 1080.
3. Quick In-Game Attempts:
   • While stuck, try Alt + Enter (toggles fullscreen).
   • Press F1 multiple times (helps refresh UI in some cases).
4. Registry Reset for Display Settings:
   • Press Win + R, type regedit.
   • Navigate under Computer\HKEY_CURRENT_USER\Software\Arvus Games\Starmaker Story and look for any Starmaker Story / Arvus-related key.
   • Delete entries starting with Screenmanager.
   • Launch the game again.

Other steps:

• Run the .exe as Administrator.
• Close any background apps with overlays (Discord, etc.).
• Ensure graphics drivers are up to date.

Start with step 1 (Bluetooth + duplicates) as that's fixed it for others with identical symptoms.

About the Event Viewer error (sysmain.dll)

This is a common Windows performance counter issue and unlikely to be the main cause of your game problem. You can try fixing it with:

cmd

lodctr /r

(run as admin). Or run sfc /scannow + DISM commands. But focus on the input stuff first.
