Server crashes when specifying IPv6 listen address

I just tried to launch the Space Engineers server with an IPv6 listen address ("::"), but it just crashes with the following output in the console:

System.IO.IOException: The process cannot access the file 'C:\Users\xxx\AppData\Roaming\SpaceEngineersDedicated\SpaceEngineersDSGUI_20240521_201144129.log' because it is being used by another process.

Changing the address back to the unspecified IPv4 address ("0.0.0.0") allows the server to start. The message regarding the log file also only happens when trying to start with the IPv6 address.

Additionally, trying to connect to an IPv6 address ("[::1]:27016") with the game results in the Error "An error occurred when parsing the provided IP address or hostname. Check the log for more details.", where the log contains the following:

2024-05-21 20:22:41.497 - Thread:   1 ->  Exception occurred: System.Net.Sockets.SocketException (0x80004005): The attempted operation is not supported for the type of object referenced

Does this game seriously not support IPv6 in 2024? :P
