I am also unable to adjust my brightness, it is stuck at full. I have tried many things, like restarting the system several times, running virus scans, resetting my graphics card, anything I could find, but nothing has changed. Any help is appreciated.

Hello, Carlo TJ. I tried a virus scan with Malwarebytes, and it told me I have no viruses. I also did a clean boot, but the issue is still happening. By the way, before the issue started, I typically had more background apps open than I do now, so I don't think the usage of memory by apps if affecting my computer.

Thank you for your help, and have a great day.

Screenshot of task manager with fewer details:

Screenshot of task manager with more details (Brave and ShareX are the only apps I normally have open, and my only starting apps. I think all the other processes are system processes, but I can screenshot them all if you want):
