MS Office file Affiliation on Windows 10

Bridge2019/ Windows 10

Whenever i double click an MS Office file in Bridge - it launches After Effects.
What i did so far:

1. Settings - Files Affiliation - does not list any  Office applications so i can not change the afiliation here (hide unaffiliated formats is unchecked)

2. All system bound affiliations are correct and working properly. Even the highest admin level connects office files correctly to its app.

3. Reset preferences and restarted multiple times.

What works is: drag and drop the Office file from Bridge into the launched Office application. But that hardly is a long term solution.

Best,
