[Help] Can't start get to menu in KH 1.5

I've been trying to play KH 1.5 for the last few days but can't get to the menu. I've looked all over the internet but most of the advice is from 2018. Nothing I do changes anything. I've renamed and even deleted the OPM file and fiddled with the configuration nigh endlessly. Nothing works! I have the 11th version of the emulator and I can play basically everything but final mix (KH1). It just freezes whenever I start it up. I don't even get to the menu.
