LOL DUDE

Okay, here's mine. I'm not in a good position at the moment to try the thing with uninstalling my tablet drivers, though, so I'll have to get back to you on that. DxDiag.txt

I have a Monoprice drawing tablet, and the appropriate drivers installed for it, though I haven't used it in some time now.

Disabling hardware acceleration worked! Paint.NET is now up and running just as it was before the update. Thank you!

Wait, actually, it turned out that I already installed Windows 10 v1803 on 22 May 2018, which is when the crashes started. So, the update that I've been attributing these crashes to is, in fact, v1803. Paint.NET worked perfectly fine before it.

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.

Ever since the latest Windows 10 update (not sure which one exactly, but I know that it added alternate log-in options when you're booting it up), Paint.NET has been immediately crashing for me on startup. It loads the window, says it's not responding for half a second, and then closes. I'm not sure if the crash log is the exact same every time, but, here's what it gave me last time: Edit by Rick: Added error code to title so I can find this post easier pdncrash.21.log
