It crash with fabric 1.17
Below i attach the log file of the crash:

https://pastebin.com/AjnZcVcY

This log file does not give any information on how Sulfur & Potassium mod caused a crash.
Please look over other mods you have installed which might have caused the crash.

I've already done it before making this ticket,
With your mod crash, without no.
Maybe it's an incompatibility, but idk because i don't understand nothing about minecraft logs files.

If you could send me your mods folder I can try look at it myself. You should be able to zip the mods folder and drag and drop it here.

It don't let me upload the zip file, so i create a dropbox link with the list of the mods:

Thanks for the mods. The issue has now been fixed. It was caused by a bad filename which meant that the log did not say anything about what was actually wrong.
