None of that worked. I got onto Nvidia's live chat and followed their instructions, which, after everything failed, led to a reinstallation of Windows and updating the Nvidia graphics card. Still exactly the same.

Thanks, Rick and Tactilis, I tried updating the NVIDIA driver both using the Lenovo Support Bridge, which failed, and then from softpedia.com, which also failed to install. Windows Update reports that everything including optional things is up-to-date. Solved the paint.net problem by going to Paint.net's settings > Graphics > Rendering device and changing that to Intel HD Graphics 530 instead of NVIDIA GeForce 930A. Also re-enabled Use hardware acceleration. Now working OK.

I've just reinstalled Windows 10 on my PC and have v. 5.0.12 of Paint.net freshly installed on it. I have now re-encountered a problem I have had before with weird flashing and glitching when trying to use the wand magic. It looks like a hardware problem, except that it's only affecting the paint.net image, not the whole screen, which seems evidence against that. I have attached the diagnostics report below and an image showing this and have uploaded a video showing the flashing to https://www.dropbox.com/scl/fi/t69uowhkwxynbki1sv2wa/Paint.net-glitch.mp4?rlkey=ngbxjsopd03anva1816auxyvx&dl=0. I am also running Wondershare Filmora v 12 and ScreenPal. As I say, I had this problem before and either I solved it or it solved itself, but I have no idea how, so any help is much appreciated.
