B580 Resizable BAR keeps disabling itself after driver updates

Hello, I have an Intel B580, a A320M-S2H motherboard, 16 GB of 2666 MHz RAM, a Ryzen 7 5700, and a certified 650W power supply. My drives are formatted as GPT, and I have updated everything to the latest versions. I was unable to enable Resizable BAR when I first bought the GPU. Intel's software showed that it was disabled, while in the BIOS it was still set to "Auto." I disabled CSM, but after saving the settings and restarting, the screen would remain black. This forced me to restart the PC, and when it booted back up, both GPU-Z and Intel's software showed that Resizable BAR was disabled. C

🐣 What this means for you
A graphics driver update. PC players with that hardware can update for bug fixes and better performance. Console players can ignore this one. Relevant to: PC.
