[IMEN] Invalid hash given error on firmware 22.1.0

[Ronin2024630]

Console: Erista (V1 Patched/Unpatched)
Firmware Version: 22.1.0
NCA Count: 455

Steps taken:

1. Dumped firmware fresh via TegraExplorer-Ext (Scripts > FirmwareDump.te > Dump sysmmc)
2. Generated prod.keys fresh via Lockpick_RCM_Pro v2.0.3
3. Tried EmmcHaccGen.CLI v3.1.0 directly with --fix-hashes flag - same error
4. Tried through NAND Fix Pro v2.2.1, Level 2: Full Rebuild - same error

Error:
[Exception] [IMEN] Invalid hash given
at EmmcHaccGen.imkv.Imen.AddContentNca()
at EmmcHaccGen.imkv.Imen.GenValue()
at EmmcHaccGen.imkv.Imen.Gen()
at EmmcHaccGen.imkv.Imen..ctor(List1 pair) at EmmcHaccGen.imkv.Imkv.Build() at EmmcHaccGen.imkv.Imkv..ctor(NcaIndexer ncaIndex, List1 skipTitles)
at EmmcHaccGen.LibEmmcHaccGen.WriteSystem(...)

BOOT0, BOOT1, BCPKG2 files generate successfully but System generation fails at imkvdb build step. Re-dumping firmware from scratch does not fix it, so likely not a corrupted dump.

I need to see your keys, please upload it here.

are you absolutely sure you need to see their keys? totally and completely sure?
I would think 455 ncas might be of more concern but I mean if you want to steal their keys don't let me stop you

i cannot use your keys on my console bro. and cannot ban your console too because i am sure there are something wrong with the keys so emmchaccgen cannot generate the files.
