I can't find the folder either. I only have the folder amplitude studios there

then Humanchild and then Mount and Containers but both are empty.

Username is Skeksys, Gamertag Skeksys222013

I've tried to find any logs in the Appdata folders which pertain to Humankind and found the player.log which appears to have a number of errors in it relating to the below

Corruptdjosh is my Gamertag after changing it to try to fix this issue... I am not sure if anyone else has mentioned it but the lobby attempts to load, then fails.. It appears its unable to fetch our gamertags as shown in this screenshot in the upper left that I was able to take before it kicked me.. the teams and everything else loads prior to being disconnected but the name in the upper left never does. . 




To add to this, I have also tried the following : Fixes attempted: New Xbox Live account, rebooting, resetting network settings, resetting router/modem, trying different ISP, ensuring all ports are forwarded, resetting the app through windows apps & features, signing out of Microsoft store and xbox app and launching the game before signing back in, revoking humankind access to xbox then re-allowing access. Also I tried deleting the humankind folder within C:\Users\<Username>\Documents. 

Partial fix for me was to create a new Gamertag and switch profiles to it.. this allowed me to create a lobby, however the friend I was attempting to play with was unable to join it as he was having the same issue and switching gamertags / profiles for him did not work.

In the small chance that a live capture helps at all, heres a ScreenToGif of the issue happening.. I trimmed it down for size restrictions.

Xbox name is "Helix Titan"

As others have said I do not have have XGP.log anywhere on my PC and I have the hidden files set up to be visible.

Same issue here. Playing through Xbox Game Pass on PC, I get forcibly kicked when trying to join multiplayer. I've managed to get the game to recognize my Xbox profile about 5 out of 50 tries, roughly. I have not found a link between the successful attempts. Sometimes I'm logged beforehand, sometimes not. I've started from the desktop, the Xbox app, and as administrator.

Gamer tag: DawnDragon

There is an Amplitude and Humankind appdata folder that was hidden, but I cannot locate an Amplitude.Interop.XGP.log file there.

I am attaching the last two diagnostics files. In the 1714 file, I was successful in joining multiplayer. In the 1709 file, I was kicked from multiplayer. You can see at around line 19, just before the first warning lines, one shows my gamertag and the other does not.
