Hello Rafapadilla,
Welcome to Microsoft Community.
After fully reading everything you posted here, I noticed that you performed a "fresh install" on your Surface Pro 9. Please allow me to confirm with you that you followed the instructions in the support link below for a fresh installation:
Windows 11 Clean Installation (microsoft.com)
Let me kindly remind you here that this is not the process for Surface, because Windows installed through this step may lack Surface specific drivers and cause various exceptions.
So, please let me share the video steps for recovering Surface devices using USB recovery drive here:
Creating and using a USB recovery drive for Surface - Microsoft Support
Following this process will restore your Surface device to factory Settings. After you complete this process, you can double check whether the problem will occur again, which will help us determine whether the source of the problem is the system or the Microsoft account.
I will wait here for your reply.
Best Regards,
Mitchell | Microsoft Community Support Specialist
