Same for me. Today I have purchased and installed the A220 in MSFS2024, but I could not operate the aircraft at all. Some of the EFB functions do work, but setting for instance the aircraft status was not happening. I have followed the troubleshooting from inKyle, I deleted the existing iniManager as explained, and I installed the latest iniManager version (2.6.0). I have checked in the MSFS2024 Marketplace, if there is any other A220 installation avalable. There is one ASOBO A220 Family stream, which cannot be deactivated or uninstalled. I have tried to delete the file in the MSFS 2024 Store folder, with the effect, that it has been reinstalled, when starting the MSFS 2024 simulator. I have uninstalled and reinstalled the A220. Nothing changed, the A220 is still not serviceable. I find it very irritating. I have many different airliners in my Library, including some from iniBuilds. This is the first time that this happens. I expect, that there is an explanation and a solution for this issue.
