ikvmnet
The newest minecraft launcher+minecraft server jar's give errors.
This is Windows 11 x64 using 8.2.1-tools-ikvm-netcoreapp on .net 6.0.3.
The newest minecraft launcher jar is outdated. However, launching minecraft 1.0 from a launcher that is not outdated opens a terminal and closes 2 times, with or without -jar and with, the launcher doesn't re-open but stays inactive and needs to be closed from task manager (the newest version just says jvm's incompatible and needs the built in).
The old jar and server actually give output when run from the cmd, although the first line is about the unsupported awt, so u might skip to the server.jar.

Is this useful information for the improvement of ikvm, or do you recommend me to try other things? latest.log
IKVM at this point does not support AWT.
The second error is about an unsupported class file version. IKVM only implements and supports JDK8. A JAR file containing classes compiled for JDK9 and above will not work.
