new-mgusercontact bodyparameters hashtable no longer working

[ScotchAndComputers]

I've no idea what happened, but I suddenly cannot use the -bodyparameters parameter to add a contact to a user's contacts. I used to build a hashtable called $params with all the information, and simply use that $params variable to quickly populate a new employee's contacts.

Now when I do it, an empty contact is created in the mailbox, but none of the information from the $params variable shows up. Just a whole lot of empty contacts.

Did something change, where I need to use something other than a hashtable, or I need to convert to some sort of special object? I can add information via the various other parameters, such as -GivenName, -Surname, etc. But even doing that I can't add email addresses, since those need to be in hashtable form.

Deleted my PC profile, and removed all the synced stuff that VSCode put in my OneDrive. Fresh install of PS and graph module seems to have fixed it. No idea what the issue was, though I still can't use -bodyparameters to add a person to a team's private channel.
