Is the Teams add-in disabled? In the desktop version of Outlook, go to File > Options > Add-ins (far left pane) > and in the drop-down menu for Manage: select Disabled Items and then select the Go... button. Do you see a Teams add-in listed in that section? If you do, select it and then select the Enable button.
Perhaps install Teams classic app back onto a device to see if it makes an impact? Microsoft still offers (at least currently) the classic installation of Teams classic. You can access it directly by going to https://go.microsoft.com/fwlink/?linkid=2187327
In case the link doesn't work for the future, you can (currently) navigate there manually by going to Teams.com, selecting Download Teams in the upper right corner, scroll down past the initial download option (which is for Teams 2.0) and look at the FAQ collapsible options. Expand the answer to the What does this mean for the classic Teams customers? question, and there will be a Download the class Teams app > hyperlink available for you to click.
For a PC that we were testing Teams 2.0 (on a GCC tenant - so I can't promise any of this will work) we had uninstalled the original Teams application and only had Teams 2.0 installed. Once we reinstalled the Teams classic app the Add-In functionality was restored in the Outlook desktop application. I believe we did have to select "Swap to classic Teams" (or something around those lines) after installing and launching Teams classic, for the add-in to start working again, but afterwards we could swap back to Teams 2.0 and the add-in was still using the classic Teams. (Or I'm guessing it is using Teams classic for the Outlook add-in at least. I may also have been impatient and reverted back to classic Teams when we didn't need to after launching the Teams classic app - since you can use Teams 2.0 after the add-in functionality was restored.)

- The Teams Add-in was enabled in Outlook when the error occurred
- Uninstalling Teams 2.0 + 1.0, delöeting the cache, downloading Teams 1.0 and reinstalling it "solved" the problem -> but it works only under Teams 1.0, if you switch to 2.0, the error is back again
