If you try to launch Java 1.21.1 or above from the official launcher with RivaTuner running, it will get stuck on a certain point (https://mclo.gs/qH6R4nZ ). Launching from Modrinth works fine, which is why I’m making a ticket for the Launcher, as I believe this issue could be on the launcher’s end (like the java version check issue previously). There’s a ticket for this on the Java Edition page (MC-296200 ).
