👨‍👧 After accepting a Party by clicking a (+) button, a player gets NullReferenceException

[BoQsc]

NullReferenceException: Object Reference not set to an instance of an object.

Since the problem is client side, I tried to look up the logs in the 7DaysToDie_Data folder:

C:\Program Files (x86)\Steam\steamapps\common\7 Days To Die\7DaysToDie_Data

After triggering this Error.

It resloves itself after printing these Error messages for about a minute or less.
Then with a use of a escape button the console can be closed to continue the gameplay.
However it does not add you to the party. Therefore still needs resolution from the server owner.

After disabling the 7DTD-fpsHUD UI MOD it resolved.
