I did learn more about that code and did get closer to compiling the right source package for my modified version. Identifying "problem" torrents:

3 hours and 30 minutes after qBittorrent launched, these still have a status of "checking resume data" (problem = it tries to check all 8 all at once):

File "trntbyte.py" is from https://ipfs.hypha.coop/ipfs/bafybeichaavxmy74lsp2wfckw6lbycvuincfghinjjvxsma5ki2mkmuaam
1. "$ sudo apt install pip python3 -y"
2. "$ pip install --break-system-packages bencodepy"

Roughly how many paths are in those? Answer: 110373 + 257457 + 75999 + 34654 + 6097 + 8410 + 8258 + 7980 = about 509,200. Image from  >>/11160/ - animation error, lidded eyes, Pinkie Pie
