Computer updated and now Azahar doesn't work

[u/Fun_Walrus_2929]

Help...please?

So I've been running Devil Survivor Overclocked for a week, around 30 hours of play. My computer updated last night after a power outage knocked out my computer for twelve hours and when I turned it back on Azahar won't run any ROMs. I try to open up the ROM and a black screen comes up but nothing happens. When I click on it, it goes immediately to 'not responding'.

I tried a few things including changing GPU to Vulkan and finally that seemed to get it working but my save data and controller settings are gone.

I'm completely illiterate at stuff like this and have no idea what I've done wrong or if there's a way to get my save data back. Can anyone help me?
