Usually, the solution is to uninstall MSI Center with the >>MSI CENTER UNINSTALLER TOOL<< and until they fix it, just don't sign in again after reinstalling. There isn't really much of a benefit to signing in anyway TBH.
it seems like some of the features and SDK are outdated, can you update to the latest version first?
recommended using this tool to remove MSI Center first, then install the latest version again.
