Hi @SamDiz ,
It seems that you have tried many suggestions to help you troubleshoot this problem.
In my opinion you can try to run uninstall support tool to help you completely uninstall Office and re-install Office application, please follow the option 2 to download the tool:

If this issue still existed, try to re-install Windows 10 and check the result.
