SUMMARY

I have a rather large multi-volume 7zip archive that Ark refuses to open. The error given is:

Loading the archive <filename> failed with the following error:
The archive may be corrupt or has header-encryption, which is currently not supported.

However, I have checked the integrity of the archive using 7zz t <filename> and it said "Everything is Ok".

I don't know how to produce another archive that has the same issue, so I will link where I downloaded it from here. Note that the archive contains NSFW content.

STEPS TO REPRODUCE
1. Download the archive from https://sukebei.nyaa.si/view/4219127
2. Try opening COM3D2_EN.7z.001 with Ark.
3. It gives the error mentioned above.

OBSERVED RESULT

Ark states that the archive is corrupted even though it wasn't.

EXPECTED RESULT

Ark successfully opens the archive.
