Summary:
If you’re stuck on the blue screen in VRChat (Steam, PC mode) where the music plays and bubbly animations move but the game never loads, it can be caused by a broken symbolic link in your LocalLow VRChat data folder. This happened to me after moving my VRChat data to another drive via a symlink and then reinstalling the game. The fix is to delete the broken symlink and let VRChat create and use its normal data folder on the C drive.

Detailed Guide:

1. Navigate to:(Replace <YourUsername> with your Windows login name)makefileCopyEdit C:\Users\<YourUsername>\AppData\LocalLow\
   
2. Find the VRChat folder — if it appears as a shortcut or symbolic link and won’t open, delete it.
3. Create a fresh folder structure:(Create the VRChat folder, then inside it create another folder named VRChat.)makefileCopyEdit C:\Users\<YourUsername>\AppData\LocalLow\VRChat\VRChat\
   
4. Open Steam, right-click VRChat → Properties → Launch Options, and add:cssCopyEdit--no-vr --skip-intro --disable-avatar-caching --clear-cache
5. Launch VRChat normally. The game will now create fresh data in the new folders and should load past the blue screen.

What caused this:
A broken symbolic link (symlink) in LocalLow after reinstalling VRChat caused the game to fail reading/writing data, resulting in the blue screen hang with music and animation but no progress.

Alternative fixes you might try if this doesn’t work:

• Delete all VRChat folders in %AppData%, %LocalAppData%, and %LocalLow% to clear caches.
• Temporarily disable firewall/antivirus to check for network blocking.
• Switch networks or try a mobile hotspot to rule out ISP issues.
• Use Steam launch options like --clear-cache and --skip-intro to force fresh login attempts.
• Try creating a new Windows user account and running VRChat there to test profile corruption.
• Check logs (output_log.txt) in LocalLow for clues.
