I always get the following errors when starting SkyFactory3 - normal Vanilla works without problems. I'm grateful for any help

"Exit Code: 0" means "Successfully executed". This is a mistake. There should actually be a different code there.
Go to Settings in the launcher and check the Open output log when Minecraft: Java Edition starts.
If the "Minecraft game output" window opens when you start, remove the checkmark from info. There should be an exit code (marked in red). This exit code is necessary to correct the error.
