I tried about everything that you recommended, and it's still not working, giving me the same error code. I updated my NVIDIA GeForce Game Ready Driver to v397.93, but I was unable to update my Intel Graphics Driver to v24.20.100.6094 because it's not "validated for [my] computer". The current version of it on my PC is v24.20.100.4691, I believe. Also, I have opened the NVIDIA control panel before and fiddled with the settings, but I had thought I had set them all back to default. I don't even know what I might have changed that would result in Paint.NET suddenly crashing on startup like this.
