Crashing without any mods

[u4h]

I don't know if It was my fault that forge dosn't load (Ingame settings) or if it is something else. And somehow I only get this error on 1.13 Forge and 1.14 Forge but not on 1.8 Forge, 1.12 Forge, 1.13 Vanilla or 1.14 Vanilla Minecraft

 

The game crashed whilst rendering overlay

Error: com.electrowill.nightconfig.core.io.ParsingException:

Not enough data available

 

For me it looks like a "Not enough Memory to use" message.

Where can I find this files?

Im confused. I mean like in C:\Users/User/AppData\Roaming\.minecraft or somewhere else. I'm not that good when it gets to exactly finding files

I think it's one of my mod configs, because it always crashes when  it says "Loading mod configs". Thanks for your help. I'm going to delete some config files from unused mods now.

Yes, it workes now. Thanks again for helping
