Hello and a happy new Year to all,
i for myself was able to fix this problem, but as i have done many things, i do not really know which was the real solution. Here the steps in inverse chronogical view (newer first).
- Activating Tablet and Ink input services (was off)
- Removing all messenger and facebook entries from registry (fbmessenger, fb-messenger, facebook)
- general sytem health and intergrity checkups (DISM and SFC/scannow)
- Installing latest updates.
- logging off from Microsoft account
- Several uninstall, cleanup and reinstall of Messender Desktop (the point where here was stuck).
Hope i was able to help. In bad case you have to do all the stuff, but i reccommend to first activate Tablet and Ink Support, if it maybe was deactivated by an update or one of the known "optimization tools",
maybe accidentaly by the user, because it tells you it is safe to deactivate. ( I also dit, SIGH! )
Greetings.....
