I have. The Windows Defender and the screen where it asks me to install it or not always appears before installing your modpack. This is the first time the bug occurred. I eventually tried reinstalling it and also deleted game caches and DL as you have shown here.
It actually worked, albeit I have to rebind the keys all over again. While on that topic, is it related to your modpack that every once in a while, the settings are reset, especially the graphics to just all of a sudden to MAXIMUM?
Looking forward for your reply.
Thank you.
