.ipsApp_front is also a class on the body element, so you need to remove the space (I've also moved that class to the front of the selector for clarity):
body.ipsApp_front[data-pageapp="forums"][data-pagemodule="forums"][data-pagecontroller="index"] .ipsBreadcrumb {
display: none !important;
}
An alternative way is using the data-pagelocation attribute in the same way you've used the others, since that tells you whether it's 'front' or 'admin':
body[data-pagelocation="front"][data-pageapp="forums"][data-pagemodule="forums"][data-pagecontroller="index"] .ipsBreadcrumb {
display: none !important;
}
Either of those approaches should work 🙂
