Hey Trudla,
Sorry for the extremely late reply! It seems like I completely forgot about this post.
There was a bug in Wurst 7.46.6 that most likely was the cause of your crash. That has since been fixed (I believe as of v7.48.1), so now Wurst works properly with Sinytra Connector.
Updating this thread now with instructions since a lot of people are finding it in search results:
How to use Wurst with NeoForge
NeoForge 1.21.1
- Add the latest Wurst version for Minecraft 1.21.1 to your mods folder (link)
- Don't add Fabric API
- Instead, add the latest Forgified Fabric API for 1.21.1 (link)
- Add Sinytra Connector for 1.21.1 (link)
- Install NeoForge (no need to install Fabric)
Forge/NeoForge 1.20.1
- Add the latest Wurst version for Minecraft 1.20.1 to your mods folder (link)
- Don't add Fabric API
- Instead, add the latest Forgified Fabric API for 1.20.1 (link) (it says Forge, but works with NeoForge too)
- Add Sinytra Connector for 1.20.1 (link) (it says Forge, but works with NeoForge too)
- Install either Forge or NeoForge (no need to install Fabric)
Important: If you find older forum posts telling you to downgrade Wurst, Forgified Fabric API, or Sodium, ignore that advice! Those compatibility issues have been fixed and the latest versions work fine now.
