No symbol table present in binary file
No matches via code heuristics
Could not process IL2CPP image. This may mean the binary file is packed, encrypted or obfuscated in a way Il2CppInspector cannot process, that the file is not an I
L2CPP image or that Il2CppInspector was not able to automatically find the required data.
Please ensure you have downloaded and installed the latest set of core plugins and try again. Check the binary file in a disassembler to ensure that it is a valid 
IL2CPP binary before submitting a bug report!
