Can't start older SD.Next with 2.15.x

[afbagwell]

What happened?

I have a pinned version of SD.Next from early 2024.
With the 2.15.x release line, I can not longer start this instance. It always throws the following error:

: error: unrecognized arguments: --uv

This error does not appear in StabilityMatrix 2.14.3 and the app starts up as normal. I've tried to debug the startup but am unable to locate the source of the "--uv" argument that SD.Next doesn't recognize, but it's not coming from any flag I'm setting manually so I assume SM is providing it by default.

Steps to reproduce

Install an older version of SD.Next (for example, commit hash 9bf08c54) and attempt to run it in SD.Next.
