That's because of a change in the code to support the current iteration path (CurrentIterationSpecialValue) when creating a workitem from an email.

var teamConfig = _tfsStore.TeamProjectCollection.GetService<Microsoft.TeamFoundation.ProcessConfiguration.Client.TeamSettingsConfigurationService>().GetTeamConfigurationsForUser(new[] { _tfsProject.Uri.ToString() }); if (teamConfig != null) { _teamSettings = teamConfig.First().TeamSettings; }

In case the current user doesn't have the right or there are no default team iterations defined, First() will fail. (the team name is not given, so TFS will take the default team settings)
Better use:
_teamSettings = teamConfig.FirstOrDefault()?.TeamSettings;

_teamSettings will contain the team settings or be null if no team settings.
The code further on using _teamSettings is checking if _teamSettings is different from null before trying to set the current iteration, so no problem.

I had the same problem as you. I'm trying to find why my user doesn't get team settings.
Searching in our DevOps server, but for the moment no luck to find it :-(

A little follow-up, in case somebody is passing by with the same problem.
Other projects did take all my time, so restarted this recently.

In order to get this to work, your account, running Mail2Bug, must be member of the project default team to get the current iteration path. In the calling code, a specific team is not provided, so TFS or DevOps will take the default project team by default.

You can quickly test if the configuration is correct by launching Chrome for example under the account used to run Mail2Bug:
https://YourDevOpsServer/tfs/YourCollection/YourProject/_apis/work/teamsettings?api-version=4.1

This api call should return the wanted information. If you see an exception in the return json message, there is still an issue in the configuration : your Mail2Bug account is still not a member of the default project team...
