1.20.1 Crash "duplicate mods found" Rubidium, embeddium

[bleachhhh]

Bug Description

I recently updated the Create mod on a modpack I have been using on the same version for around a year now. After launching, the crash report stated that I had an outdated version of Embeddium. After updating the mod, It then stated in the crash report

[main/ERROR]: Found duplicate mods:
Mod ID: 'rubidium' from mod files: xenon-1.20.1-0.3.1.jar, embeddium-0.3.30+mc1.20.1.jar
Mod ID: 'embeddium' from mod files: xenon-1.20.1-0.3.1.jar, embeddium-0.3.30+mc1.20.1.jar"

I don't have rubidium in the mod folder after searching. I have tried removing the mod and readding it, but that hasn't worked either. Any idea of what caused this?

Reproduction Steps

1. Download Better MC [FORGE] - BMC4, 1.20.1, v26
2. Download the latest version of Create mod
3. Update embeddium to the latest version

Your modpack has Xenon in it, it's basically the same thing as Embeddium. Just use either one
