When we are loading ICO (icon files) using 'ImageList.ListImages.Add' method in VB6 code, it is throwing "runtime error 7 - out of memory" message. It is working when ICO files are loaded using LoadPicture method, in a Windows 11 PC with Insider Build 22567.100. It is working fine with older Windows 11 builds and issue is occurring only in this build.
For BMP files it is working fine with 'ImageList.ListImages.Add' method, and error is occurring only for ICO files. We are using ICO files with bit depth as 32.
