Every time I load Minecraft Launcher with Abnormals core installed, it crashes when loading config. Without Abnormals Core installed, I can't use Endergetic and Abundance. I don"t want to lose all my stuff that I found

We can't help out much without a crash report.
Deleting the config for Abnormals Core should fix the crash if the crash is related to the Abnormals Core config.

We can't do much without a crash report, so please send it.
The config may be crashing due to a parsing error in the config file. I recommend deleting the Abnormals Core config and seeing if that stops the crash from occurring.

How do you sent a crashing report and how do you delete the abnormals core config?Beacause i have the same problem

actually, my entire config file was corrupted so i just had to remove the entire file and it worked

what do you mean with remove the entire file?

didnt solved problem

okay let me explain.
You have to access your .minecraft file
in it you should see your config file
just drag it out of the folder then you're done

I'm having the same problem, my game keeps crashing. I looked in my config folder but I'm not seeing a config file for this mod at all

Due to the lack of activity and given solutions to the issue, this is getting closed.
If the issue persists, it can get discussed here. This issue is not directly caused by Abnormals Core as it's just a config file error.
