I get this error when I try on a jar

Deobfuscation failed. Please open a ticket on GitHub and provide the following error:

It has to do with the Java version I think, but I tried running the deobfuscator with Java 8 (my default) and Java 17 but both result in this error, I know that Java 17 uses major version 61 so what would be the issue here?

Figured it out, saw the other issue on the old asm and figured I was using the old version, only issue that still stands is the jackson issue which already mentioned in someones issue.
