Did "most of the data" include the entire ~2MB LUKS header? You need at least the first 256KB to get all the stripes of the first keyslot. If that data is not all bit-for-bit perfect, the master key cannot be recovered and your data cannot be decrypted. You can look at section 4.2 of the cryptsetup FAQ at <https://gitlab.com/cryptsetup/cryptsetup/wikis/FrequentlyAskedQuestions#4-troubleshooting> for information on how to build and run a keyslot checker that can test for obvious damage to the keyslots ("obvious" meaning "data with low entropy appearing in places that should appear random").
I think the partition layout might be relevant, as there is only a 2
space between the EXT and Linux partitions.
Your partition layout is fine. Logical partitions (numbers 5 and higher) exist within the extended partition. All that is needed is space for the 1-sector extended partition header before the start of partition 5.
