As title says latest (rsinfinitybooster-neoforge-1.20.4-1.0.0.34.jar) are built targetting JAVA 21 (class file version 65.0). Since minectraft is bundled with either JDK 17 or JRE8 then the mod/jar does not load using builtin JDK17/JRE8 (or any other JDK/JRE lesser than 21).
Same goes for aeinfinitybooster-neoforge-1.20.4-1.0.1.33.jar.
