Hi Greg,
I'm also having the same issue since installing the latest patch for Windows 11 (Windows 11, version 22H2) whenever I try to open an image file with Microsoft's Paint 3D. I get the "No such interface supported" error message when opening files either through the "Default app/File type" settings or through the contextual menu "Open with". Paint 3D is working just fine on its own and it can still open any file through its own "Open" menu. I've tried repairing the app through Windows' Installed app menu but it didn't work. With these few reports of different file types creating that issue but not systematically the same for everyone, it does seems like the patch broke something that is not app specific. So far, images are the only file type for which I'm having the issue, and of the many image editing apps I have, Paint 3D seems to be the only one that broke for me.
Any suggestions would be appreciated.
Thanks
