What version of the mod, Forge/Neoforge and Minecraft are you using?
Forge 1.19.2 | 43.3.2

Describe the bug
Server crashes after updating mod to version 1.1

To Reproduce
Steps to reproduce the behavior:

1. Launch server with Redux v1.1 installed, along with the other mods I have installed (see crash report for mod list)
2. See server crash with message: The Aether: Redux (aether_redux) has failed to load correctly
   §7java.lang.ExceptionInInitializerError: null

Expected behavior
Server starts up without problems while having Redux v1.1 installed, just like it did with Redux v1.0.5.

Log file (should be titled latest.log, if applicable)

Additional context
Worked fine on v1.0.5, crash only occurs after updating to v1.1

Extra info: client (same Forge version) launches just fine, no crashes on client

happens also in 1.20.1 with forge 47.2.1.
the mod wants to load a client gui, (java.lang.RuntimeException: Attempted to load class net/minecraft/client/gui/components/AbstractWidget for invalid dist DEDICATED_SERVER)

this will be fixed in v1.2, which should come out relatively soon
luckily it wasn't a super hard bug to fix, just some client code being accidentally loaded on the server

fixed, in version 1.2!
