This appears to be a bug in NVIDIAs driver.$$$Fixed effects calling Dispose() on the IServiceProvider when they shouldnt have been. This affected plugins like CodeLab and Plugin Browser.$$$Updated the bundled AVIF FileType to version 3.11.0.0 (thanks @null54!)

Paint.NET 5.1 is now available!$$$$$$Posted November 12$$$$$$This is a major update to Paint.NET that includes a raft of technology upgrades including full color management; support for HDR and Wide Color Gamut displays; major improvements to input latency and memory usage; and new and revamped blur effects. In addition; the migration of effects and adjustments to the GPU has been completed; further improving their performance and quality. There are also some new canvas customization settings.$$$$$$ $$$$$$Color Management$$$$$$Paint.NET finally has full color management support; a feature commonly found in more expensive or complicated imaging software. This ensures that images with embedded color profiles look the way theyre supposed to; as originally captured by a camera or as intended by the author. Most cellphone cameras nowadays will take photos in a wide gamut color space like Display P3; and now those photos will have correct colors; brightness; and saturation when opened in Paint.NET.$$$$$$ $$$$$$Heres an example using a NASA photograph of the Cosmic Cliffs nebula taken by the James Webb telescope (source). It was captured in infrared and then shifted to the visible light spectrum; and the final result uses the ProPhoto RGB color space so as to utilize a very large spectrum of colors.$$$$$$On the left is how the image looks if the color profile is ignored; as youd see in Paint.NET 5.0 and earlier. On the right; however; the color profile is being applied in real-time to ensure that everything looks exactly as NASA intended it to.$$$$$$ $$$$$$Color Management is configured in Settings; but there isnt much that needs to be configured. Windows Advanced Color; enabled by default; is used to provide one-click color management support for your display. When the display is configured for High Dynamic Range (HDR) or Wide Color Gamut (WCG) mode; this enables high bit-depth output (e.g. 10-bits or more) and use of the displays full color gamut. Windows then ensures accurate and consistent color reproduction; based on what the display itself tells the system via EDID.$$$$$$ $$$$$$Displays configured for Standard Dynamic Range (SDR) do not support Windows Advanced Color; so Paint.NET will run in sRGB mode which ensures consistent color reproduction. Color accuracy is then dependent on the display itself being configured for sRGB color output.$$$$$$ $$$$$$There are instructions to guide you through enabling HDR or WCG for your display over in Windows Display Settings. A status section gives clear information about the state of color management and the display:
