I suddenly can't run Lossless Scaling

[𝔻ℝ𝔸𝔾𝕆ℕ]

I'm not sure when it started or what changed with my computer, but the software suddenly won't launch when I try to run it. Here's what's happening:

Beta version: No error messages at all – it just fails to start.

Legacy 3.0 and earlier versions: I get this error:
"The settings file is corrupted. Instance validation error: 'LSFG3' is not a valid value for FrameGenerationEnum. at System.Xml.Serialization.XmlSerializer.Deserialize(XmlReader..."
Oldest 1.6 version: It launches but is completely non-functional.

I’ve tried basic troubleshooting like restarting my PC and running as administrator, but nothing works. Strangely, the software runs perfectly on my office computer. I really don’t want to reinstall my OS just to fix this. Could you please help me resolve this issue without requiring a system reset? I’d greatly appreciate any guidance to get the software working again! 🙏

Uninstall, delete everything and anything residual relating to lsfg and then reinstall.

Or simply try verifying files.
