The game crashed whilst initializing game
Error: java.lang.RuntimeException: Could not execute entrypoint stage 'main' due to errors, provided by 'fabric-networking-api-v1'!

Post the crash log or .minecraft/logs/latest.log file to some pastebin service. This isn't enough information to know anything about he cause yet. One obvious thing is to check that you have the mod (all the mods) for the correct MC version.
