I don't know if my issue is related to #1874 or not

With verbose flag I see the same brut output

FINE: Config flags size > 56, but exceeding bytes are all zero, so it should be ok.

Not sure on this yet, seems to be crashing out on internal resources which doesn't make much sense.

Additional information: I can decompile it using jadx

I replicate. Adding Bug.

I'm closing as the original crash is now resolved (the invalid chunk type).

You can rebuild assuming you fix that one undecoded resource, which is the resource for the splits.

Which then becomes a known issue :/ - #2514

So I feel its safe to close this one now as the remaining issue is tracked elsewhere.
