🪲 'Connect-MgGraph: Entry point was not found'. Error when running Maester

[O365-Zende]

Pre-submission checklist

• I can reproduce this issue using the latest released version of Maester.
• I have searched the existing issues and did not find a similar report.

Describe the bug

Run Measter as normal, update everything, then connect.
Partway through when it tries to get Graph operational, it hits an error

Steps to reproduce

Connect-Maester -Service All -TenantId "" -SharePointClientId "" -SharePointAdminUrl "https://**********-admin.sharepoint.com" -Privileged

See Debug for the stop point

Expected behavior

Connect to Graph

I tested Graph separately with the standard Connect-MgGraph, and it works fine

Screenshots

Picture from a previous attempt with a diff error, but was run earlier so may not be relevant

No response

Updated all possible parts
Force update with clobber for MSGraph to overwrite, still same result when running / same error.

I also ran -Verbose as well and it only shows the red error no other info

Have not been able to run Maester at all for a while now

Small Update
I found Merill's script for removing graph etc., so I tore the lot out and started again.

Tried to connect to Maester and I still get the red error as before

Im hoping this may fix the issue
