Describe the Bug:
a server with these mods(forge version 1.16.5-36.2.0)

does not boot (it also does not generate a crashlog)

I asked the Crossroads developer: he had an idea that it is caused due mixins (i am not quite sure what that entails)

a server with these mods(forge version 1.16.5-36.2.0)

does not boot (it also does not generate a crashlog)

using the above list of mods on server causes it not to boot

i would expect it would

Operating System: debian
Mod Version: 2.2.0
Minecraft Version: 1.16.5
Forge Version:36.2.0
Other mods that were running when the crash happened: ![image](https://user-images.githubusercontent.com/12761103/130334841-42e6991b-678f-4ff9-9f75-76ecb4873ec2.png)

I asked the Crossroads developer: he had an idea that it is caused due mixins (i am not quite sure what that entails)
