Can't Screenshot no matter what I do

[AR]

I'm a modmaker and I rely on screenshots of my mods for Nexus. I've tried everything, Steam overlay is on, the Ini has screenshots allowed, no ENB, uninstalled and reinstalled. I even tried to set F12 screenshots to a different key, just nothing works. Is there any fix for this? It was working a few months before, now it isn't at all.

you need to use PrtSc key and also have the in-game anti aliasing disabled; you can force anti-aliasing through Nvidia Control Panel, Radeon Settings, or Intel Graphics Command Centre (or whatever Apple has if you're using their ARM-based Macs idk). after the screenshots are taken and you exit the game, go to where your Oblivion files are installed and you'll find them.

Drive -> Steam -> steamapps -> common -> TES IV: Oblivion GoTY Edition

but to be very honest, this game doesn't really need much anti-aliasing except for FXAA or TAA because there's not much aliasing to begin with. unless of course, you're playing at a low resolution and/or low PPI (pixels per inch) monitor; since i'm playing in FHD (1920x1080) on a gaming laptop, my display's PPI is 141, which is extremely high enough that only those post-processing based AA are needed.
