Problems to load my Mod.

Describe the bug

I had edited my UNDERTALE data.win file 2 days ago, and now I can't open it anymore. Is there some way that I can solve that?

1. I tried open the data.win file I was editing for months for a Undertale mod.
2. And when it was loading, I received this error.

Setup Details

1. UndertaleModTool Version: v0.8.4.1
2. Operating system: Windows 11 23H2
3. UNDERTALE (Version 1.08)
