[Issue]: Warning for Windows Server 2019 users

[HoraxNL]

Please describe your bug

When updating from old versions (Mine was 10.8.13) to version 10.9.2, Jellyfin 10.9.2 requires .net version 4.8.1 which is not supported on Windows Server 2019.

.net 4.8.1 only supports Windows Server 2022, see: https://learn.microsoft.com/en-us/dotnet/framework/get-started/system-requirements

Reproduction Steps

I uninstalled 10.9.2 and installed 10.8.13 again, copied the programdata and programfiles folders (My Jellyfin Backup folders) back, now it works again.

Best way (for me) is to make a new Win 2022 Server (Virtual Machine) with Jellyfin 10.9.2 and then migrate existing settings or create users and settings again..etc on the new server, when done port forward to the new server.

I have identified the same problem. I have the same setup. Jellyfin installer is just NOT performing mandatory prerequisites checks before installation. Maybe someone have figured out how to install latest .net framework 4.8.1 on Windows Server 2019? I believe switching to another OS will be obligatory.

To be honest, it was a simple oversight because it previously worked for over two years. I'll be switching it to another version that is older but it will make the installation slightly larger.
