Hi Michel Petit3,
Thank you for reaching Microsoft Community. We're sorry for the trouble this has caused you.
We recommend trying these steps below to resolve this issue.
Force the device to shut down and restart
Press and hold down the power button until your Surface shuts down and restarts and you see the Windows logo screen (about 20 seconds), then release the power button.
Check Windows Updates
Go to Settings >> Update and Security >> Windows updates >> Check for updates
Run Surface Diagnostic Toolkit
See: Fix common Surface problems using the Surface Diagnostic Toolkit (microsoft.com)
Run the system file checker to check if there are corrupted system files that are just looping around causing this kind of issue to exist.
To run the system file checker, kindly type Command Prompt on the search box next to the Windows icon and run it as administrator. Once done, type and enter sfc /scannow.
Let it load, detect and repair those corrupted files. Whether it detects a corrupted file or not, kindly restart your Surface device afterwards.
Perform a Memory Diagnostic
From Search, type Memory Diagnostic and run the Windows Memory Diagnostic program.

I hope these works.
Kind regards,
Lavenia
