i was having the problem a lot of people seem to be having, nothing would happen after launching game from launcher not even an error code spent 2 hours troubleshooting i found my antivirus(avast) had deleted 2 files after restoring these files back into ModifiableWindowsApps NOT WindowsApps that everyone keeps referencing pso2 booted up perfectly. also note when attempting to restore deleted items even though they said they where restore they had not bin and had to manually drag then from virus vault. hope this saves people hours of frustration that i went through.
