unitypack\utils.py", line 10, in lz4_decompress
return decompress(data, size)
_block.LZ4BlockError: Decompression failed: corrupt input or insufficient space in destination buffer. Error code: 222

i found that unitypack can run well in the assetBundle that packing by the untiy2018, however, it crashed in the case of untiy2019 and untiy2020;
Does anyone else have this problem?

I personally haven't run into this problem, but the file you provided indeed does cause this error.
The most likely cause is that Unity changed the type of compression in Unity2019.

Solution: Patch utils.py and assetbundle.py to provide decompression for whatever they came up with this time.

Experiencing this same issue. Non-CLI utilities not an option in my case.

I have this issue since the latest HS version (updates to Unity 2019.4.21f1). Has anyone a fix for it?

@robert-nix Hey Robert, sorry for the ping, but the repo doesn't seem too much maintained anymore, so I'm trying my last card :)
Does this issue ring any bell to you? Would you be able to know what is wrong?
Thanks a lot for your help :)
