Hello diesieben07, as I said, there is no debug.log file in my .minecraft logs file. There are only some logs from 2020 and 2021 (https://prnt.sc/10iznlm) Here you can see that I am in my logs file: https://prnt.sc/10jqok4 Its: Nico > AppData > Roaming > .minecraft > logs

Dont know what that means (Sorry) but im using the normal Minecraft Launcher

I cant find any debug.log file in there only that: https://prnt.sc/10iznlm

From where? .minecraft?

Where should I post it?
