Lip Sync Sequences stop working until rebuilt

Hey guys. I'm using UE4. Not sure if I should have posted this in Unreal Development or Avatar Development.. but this is specific to UE4 so Unreal Dev seems right.

Anyway, my issue is that the lip sync will stop working when the project is closed. So it'll work great, close project, open it again, no lip movement.

The issue is the sequence. If I right click make a new one, it works. But obviously remaking all my sequences every time I open the project is not going to cut it.

I'm using UE4 4.22.3 and the latest lip sync plugin released a few days ago.

Any ideas what I can do here?

So some more details. I'm starting to suspect the issue is with me somewhere, because none of the following work, and I'm pretty sure they did before

1.37 
1.38

4.21
4.22 

Any combination of the plugin or unreal has this same issue.

Even a fresh download won't work when I open it until I remake the Sequence.

Also, when trying to package the plugin, I get this error;

Also, the plugin only works as "third party", as in if I put the plugin folder in the project specifically. If I add it to the unreal folders, it shows up, but wants to be recompiled, and that gives an error.

Included the full log mentioned above.

Could really use some help. Love this plugin but it's old remaking all the sequences and being unable to progress.

I think the issue is not anything bad. The problem lies in the audio file itself, I am not sure how the source wav file needs to be encoded, but if you try different wav files besides the default oculus one it works fine. It works in editor and shipping builds just fine. Try some different audio files and generate the lipsync sequence and you'll see,

So my partner is now getting the errors I listed above about no such header file. 

Changing the wav file makes no difference. The C++ isn't compiling. "fatal error C1063: Cannot open include file: 'Classes/Sound/Soundwave.h": No such file or directory.

No idea how to help debug this but it's kind of on me. Searching for help just came up with my own post from a year ago, lol
