I was in the middle of a Fortnite session when lightning struck outside my apartment. Suddenly, both of my monitors went black, but I could still chat with my friend for about a minute while the PC stayed on. After that, I had to manually restart my computer. Now, my main monitor turns on, but my second monitor doesn't display at all, and I think the HDMI might be fried. The PC seems to work fine otherwise; the GPU's lights are on, and I can watch YouTube without issues. However, when I try to play games like Valorant or Fortnite, or even open the AMD Adrenaline software, I get an error. Has anyone experienced this before and know how to fix it?

Sounds like the lightning might have caused some issues. Did you have anything plugged into surge protectors or a UPS? If not, that could be a problem.
I'd suggest using DDU to completely uninstall your GPU drivers and then reinstall them. If that doesn’t work, try testing your GPU in another system if you have one available.
Thanks! I’ll give that a shot.

I don't have a battery backup, but my surge protector should be working.
