Plugging in second screen caused built-in to go black

New to linux so I'd appreciate if anyone can help me troubleshoot. I have an Asus Tuf A14, tried connecting it to my TV as a second monitor and the built in screen went black. TV is still working, and in display settings it does look like both screens are being detected, but the laptop screen doesn't work at all post-login, even if I unplug the HDMI, reboot, etc. (Works in BIOS, works on login screen, I'm dual booting with windows and it still works in windows, doesn't work once I log in to Bazzite)
CPU is AMD, GPU is Nvidia

Solution

Open the file explorer. Press CTRL+H (to show hidden files and folders) then you can just find the .config folder and rename the file in question
