bug Crashing when trying to replace a portrait

[melxdyhime]

Hiii! Well, I wanted to ask if there's any way to fix this. TT I've tried replacing the default images with new ones. I've tried JPG and PNG files, and I've also made sure to maintain the exact image resolutions and dimensions. I made sure to run the program as administrator. But when I try to replace the image and press the "Apply" button, the program crashes. I reopen it and this appears.
PD; At the changelogs I see this: >>>> [Error] Missing assembly 'S4TI.UniPlugin.dll' So, where can I find that file? On the zip I downloaded it doesn't exists. Thanks!

@melxdyhime Oops, I may have introduced a bug, will be fixed soon.
 

UniPlugin is no longer available, will fix the App Reports.

I'm having this same exact problem. 

This started for me after the most recent game update; before that it was working perfectly. 

S4TI Version 1.25.8

Game Version: 1.116.240.1020

Windows 11 and Drivers Up to Date

I keep having issues trying to replace gallery images. Application just crashes when I click "Apply". Please help, I've tried reinstalling, I have latest update for application and NET. Not sure what else to do.

I'm currently investigating what is causing the issue.
I fixed the bug that was causing the issue but I discovered another bug that can also crash the app.

 

For now the only workaround is to use an older version.

현재 문제의 원인을 조사 중입니다.
앱을 중단할 수 있는 또 다른 버그를 발견했습니다.

 

지금은 유일한 솔루션은 이전 버전을 사용하는 다.

"이전 버전을 어디서 다운로드할 수 있는지 알려주시겠어요? 사용하고 싶은데 어디에도 찾을 수 없네요. 도와주시면 정말 감사하겠습니다."
