Vintage Story servers run on the .NET runtime, and newer game versions require a newer .NET release. Version 1.22 needs .NET 10. If the server is running an older runtime, the game files cannot start at all.
New Vintage Story servers are created on .NET 10 automatically, so this only affects servers created earlier.
If your server will not start and you believe the runtime is the cause, open a ticket — we switch the runtime for you and the change takes effect on the next start. Your world and configuration are not affected.
If you need help with this, please submit a ticket.
