Outlook not working after AVG update and restart

Hello Dries.
This is the first time we came across this error message and we're not exactly sure AVG update has caused this issue.
We'd request you to uninstall and reinstall Microsoft Office 365 package to resolve the issue.

Good day

I received an update request for my AVG two days ago and downloaded it. Thereafter it requested a restart, which I did the next day. This is the only thing I have changed on my old Windows 8 Dell, running Office 365 on a license from my company.

Now when I try to open Outlook I get the following message: the required file react-native-win32.dll cannot be found in your path. Install Microsoft Outlook again.

I have done an online and quick repair and nothing has helped.

Please assist if possible.
