Hi foxypigeon,
Thank you for reaching out to Microsoft Community.
Please run these steps on your Surafce Pro 6v first then observe if still the freezing issue persist:
1: Run Surface Diagnostic Toolkit and check Windows Update
2: Update drivers and firmware
Check what is the current OS Build of your Windows version by going to Settings > System > About.
Go to Download driver and firmware for Surface, choose Surface Pro 6 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.
3: Run System File Checker Tool in Windows 10
If still the issue persist, you do have an option to return the device for refund and repurchase. You may contact support through our Global Customer Service phone numbers for assistance or the retailer if the device was bought through a 3rd party retailer.
If this answer your question, we highly encourage you to inform our Community by clicking on Yes or marking my post as an answer. This will help other members who may have the same issue as you. Otherwise, don't hesitate to update us so we can further assist you.
