Regarding usage of the deobfuscator:

You should NEVER (!!!!!!) select all transformers. The result will not be usable for anything.

Only select the transformer for the specific obfuscation you know your input has. To find out what your input has, you can tick the "detect" checkbox. It will make the deobfuscator not deobfuscate and instead only prints what obfuscation it was able to find, so you can select the first suggested transformer.

Your specific error: A class file could not be fully read as class file, it might be invalid. There seems to be a problem that its not correctly catching and continuing when this error occurred.

Problems regarding your transformer choice would occurr only later on.
