I tried to reinstall fabric and sodium but nothing changed, here is the error that I get : https://pastebin.com/eJQnguW9
Minecraft is in 1.16.1 by the way

there is a different error now : https://pastebin.com/yH0Uycpx

Your second error is #219
The solution is to delete sodium-options.json from the config folder as it has been corrupted.
I'm not sure what your first error is or whether it should be gone now. The issue tracker is intended to track bugs, not for tech support, so I recommend that you join the discord server if you need further support.

thank you very much this is working now
