Hi Alex,
Thank you for sharing your issue. I understand that you are having a problem with your Surface device keyboard, let’s sort this together.
Based on my knowledge It could be due to a few things, like driver problems, power settings, or apps not being fully ready for the ARM64 setup that Snapdragon CPUs use.
Please follow these steps.
Try running the Surface Diagnostic Toolkit to check for any problems with the hardware or software.

Turn off any antivirus to check if that is causing the problem.
May I also ask, does the freezing seem to happen more when you're using external displays or other devices? Are there any apps you're using when things freeze, or does it seem to happen out of nowhere?
Let me know if you have more to share or any questions.
Best Regards,
Noel
