Can't startup the vrchat

Help!
1

The software was working fine 2 days ago, but yesterday it won’t start up properly.

When I opened the software, EAC launched normally and a VRChat window popped up, but the screen was completely white. After five seconds, the window disappeared, and there was no further message.

I have already tried the following:
Updating the graphics card drivers and restarting: did not work
Trying desktop mode: still crashes immediately
Completely uninstalling VRChat and clearing its cache: had no effect
Completely deleting the EAC files and restarting the computer: had no effect

logs in LocalLow\VRChat\VRChatonly have 3 lines:

2026.06.08 22:18:57 Error      -  [LOCALIZATION] Keys file has more lines than en file, must have the same amount of lines.
2026.06.08 22:18:57 Debug      -  Odin Serializer ArchitectureInfo initialization with defaults (all unaligned read/writes disabled).
2026.06.08 22:18:57 Debug      -  Odin Serializer detected whitelisted runtime platform WindowsPlayer and memory read test succeeded; enabling all unaligned memory read/writes.

If the issue remains unresolved, I will try to request a refund through PayPal, I am unable to open the software.

The next line (the fourth line) in output logs is supposed to be “initialized Steam connection” on Windows. It’s plausible you didn’t have an established connection with Steam.
