In this article, we'll delve into the details of the bug, provide reproduction steps, and offer a solution to help you overcome this issue.

Bug Description

The "duplicate mods found" error message is a common issue that occurs when Minecraft detects duplicate mod IDs in the modpack. This can happen when a mod is updated, and the new version includes the same mod ID as an existing mod. In this case, the crash report indicates that the mod ID 'rubidium' is found in two mod files: xenon-1.20.1-0.3.1.jar and embeddium-0.3.30+mc1.20.1.jar. However, as you've mentioned, you don't have the rubidium mod in your mod folder, which makes it even more puzzling.
