So I had been following the Official HOI4 modding tutorial, and basically completed the beginners course. My custom mod worked fine.
And after waiting for a while, I thought about trying out the intermediary course, only for my mod now to course my game to crash whenever It tries to load up the main menu. Always at the "Initializing game" part of the opening load screen.
I'd try to figure what's wrong, but the error log is bloody error.log is 296,634 characters long, and I would not know where to start to look for the main culprit of the crash.
The main difference that I can think of that has happened is that I bought and downloaded two new DLCs. AAT and Gutter. Though I doubt that's the main issue.
