Failed to load some AnimationClips of GI

[isHarryh]

Description

Using blk files form Genshin Impact v4.5.0 (Android, global server)

When I tried to load Genshin Impact AnimationClips into Studio GUI, I saw some AnimationClips were successfully loaded and can be correctly exported. However, there were still some other AnimationClips cannot be loaded.

Console output shown below:

From the console, we can see there are two cause for this problem:

1. System.IO.EndOfStreamException: Unable to read beyond the end of the stream.
2. System.OverflowException: Arithmetic operation resulted in an overflow.

To Reproduce

Steps to reproduce the behavior:

1. Open Studio GUI and specify the target game to GI.
2. Load file 00002343.blk (or any other Genshin Impact blk file containing AnimationClips).
3. Error occurs while loading.

Version

Using Studio v1.36.00 e1d7f53

Sample

00002343.blk is provided here:

No, AnimationClips have the same data between Android and Windows GI. Only scene models are different because Android GI uses the low-quality-optimized models.

Since I want to get some specified AniamtionClips, I hope this issue can be investigated. Thank you.
