I am having the same issue with Nitrosense not opening at all, it happened all of a sudden and has been months now without any sort of resolution. I have a Acer Nitro 5 AN518-58 operating Windows 11 Home 12th Gen Intel core i5 - 12500H..Intel UHD Graphics and NVIDIA GeForce RTX 3050.
I have done the uninstall reinstall many times I have the latest BIOS and have tired several online repairs all of which failed to bring back Nitrosense. I have written to ACER and Microsoft and have the latest updates available still nothing has fixed the issue.As so many have the same issue why can't ACER offer a repair update as it is when working a great asset to be able to use the fans at max when required as well as operate the RGB lighting.
Hope sone can help us who have this issue
