This looks like a bug that only the kernel developers, or your distro's developers can fix. It's in the i915 driver, which is for your intel graphics.
The only advice I can give is to never attempt installing graphics manually, only through your distribution's built-in mechanisms, or guides specifically for the distribution (preferably from the distribution people themselves). Doing it any other way can majorly fuck your system up, especially across upgrades. As Pop_OS! is Ubuntu-based, I believe there's simply a "drivers" tab in the software sources program.
Also, if your hardware is younger than 4 years, I wouldn't recommend running a distribution that only updates every 2 years, as Pop_OS! and its base, Ubuntu do. If your hardware is younger than 2 years I don't recommend running Linux on it at all.
Sometimes, a slow-updating distro will provide "hardware enablement" packages or mechanisms to install newer kernels. Look into that and ask in the distro's forums if there's just any way to update the kernel to a more "experimental" one for your hardware. The kernel provides all the drivers, so that may help with bugs like these.
If all of the above fails, and you didn't install any drivers from external sources, simply report this bug to your distro's developers, or if you're feeling adventurous, try reporting it to the kernel bug tracker directly on
bugzilla.kernel.org. In both cases try to be as detailed as possible about your setup and the symptoms. Include the OS and kernel version.
