janhoek try checking if you have multiple office suite installed in your machine. uninstall the other and keep only 1 version of Office suite in your machine. you can do that by going to control panel > programs and features > uninstall a program. but, if you only have one version of office the next thing you have to do is to go to any office apps (e.g. word app) go to file > account > see if you only have 1 subscription open there. if you are seeing multiple subscription this will cause the interruption to resolve it you can sign out from all of your account first in office and then close all apps and reopen you need to see only 1 office suite showing in this part too. see the screenshot below with yellow circle.

you can also use cscript in command prompt to remove other office suite installed.
