[Bug]: diffsinger ritsu and ruko do not work in new update

[crkforever045-svg]

Device and System Name

Samsung A25 5G and Samsung A21s

App Version

Openutau mobile nightly build 28

Description of the Issue

I was testing if diffinger needed tweaking in the nightly ver of the app. Today and yesterday I installed the V2 rewrite of openutau mobile and along with it, Namine Ritsu DS and Yokune Ruko DS 🚺. I installed them into the app, plus nsf-hifigan and opened the editor track. First I tried using Namine Ritsu and the note was valid but then the app crashed when I tried to render it. The same happened for the Yokune Ruko voicebank but this time the note wasn't valid (?)

Steps to Reproduce

1.install newest ver of Ruko and Ritsu Diffsinger and nsf-hifigan
2.open the editor
3.choose ritsu
4.tap a note and try to play it
5.repeat step 3 and 4 this time on ruko's voicebank

(I was about to do a duplicate but I saw this)
It happens with any DiffSinger and it seems that it's a problem with the phonemizers. Here's a log:

Uh

Thank you

Are you using the PR's build? That should fix every ds-dict issue (after testing it with Ritsu and Ruko) and does not affect the UTAU engine (as I tested a few CVVC UTAU's on my end too). The PR's build is still not merged in the main project (and it'll probably end up being replaced by the Core update PR that the author opened now), so please, wait.

I am using the updated build and have used adachi rei and ended up with the same problem
