cannot decode Clash Royale sc files

Start with xc​​oder/features/sc/decode.py and xc​​oder/features/cut_sprites.py, especially render_objects where the traceback shows the failure while saving shape 0. Reproduce with 55_CannoneerTaunt_FG.sc and inspect the generated shape dimensions; done means the SC file is processed without the Pillow crash and the expected sprite output is produced.

what I did:

• placed 55_CannoneerTaunt_FG.sc from Clash Royale apk into In-Compressed, then ran the program.
  => choosing 1 does nothing, choosing 3 crashes. (logs below in code tags)
• I also placed the same file into In-Decompressed
  => choosing 1 or 3 does nothing.
• I tried with other SC files from the same apk too.
