Hi Stathis Moysiadis,
Thank you for reaching Microsoft Community. We're sorry for the trouble this has caused you.
I recommend to try these steps below.
1. 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.
2. Check Windows Updates and Run Surface Diagnostic Toolkit
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)
3. Check reliability Monitor - View Critical events listed. If issue is app specific, troubleshooting should be performed on the app (remove and reinstall and/or contact publisher)
4. Scan Surface with Windows Defender
Search Windows Security >> Virus & threat protection >> quick scan.
5 . 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.
6. Update drivers and firmware
Check what is the current OS Build of your Windows version. On the search box type Winver and run command.
Go to Download driver and firmware for Surface, choose Surface Laptop. Then click the link next to Surface Laptop Studio then click Download on the next page. Choose the .msi file that matches your current OS Build and click Next. After downloading, run and install the .msi then Restart.
Let me know how it goes.
Kind regards,
Lavenia
