Trying to extract dylibs from ipsw with the command ipsw dyld extract -a --objc --slide --stubs ./21E237__iPhone16,1/dyld_shared_cache_arm64e
on iOS 17.4.1 iPhone16,1
returns an error: failed to extract dylib /System/Library/PrivateFrameworks/CoreALD.framework/CoreALD: failed to optimize load commands: failed to remap offset in LC_ENCRYPTION_INFO_64: failed to remap offset 0x4000
Seems that running just with -a--all gives the same result, but would be nice to not fail the whole process just say which one failed and continue with the extraction.
My setup:
MBP M3 Sonoma 14.4.1
How can we reproduce this?
run ipsw dyld extract -a --objc --slide --stubs ./21E237__iPhone16,1/dyld_shared_cache_arm64e
on the extracted dyld from iPhone16,1_17.4.1_21E237_Restore.ipsw
simple echo 123 > OUTPUT_FOLDER_PATH/System/Library/PrivateFrameworks/CoreALD.framework/CoreALD "tricked" the script to go over the problematic dylib and finish extracting the rest : )
ipsw dyld extract extracted_files/21F79__iPhone11,8/dyld_shared_cache_arm64e --all --force

I've tried restarting my Mac, using --force, updating to the latest version of IPSW, but neither seem to address the issue. I also tried the comment mentioned above, but the CoreALD.framework/CoreALD path does not exist, as it hasn't been created yet.
What happened?
