Hello there,
Not sure what is the problem but you can try to update all your drivers and BIOS and check if that helps.
Is there any error message displayed while turning on memory integrity?
Go to Bios, enable hardware virtualization support, and then enable UEFI mode, Enable Secure boot and enable TPM device support.
Save and exit from bios, boot windows, then turn on Memory Integrity and see if the Touchpad error continues.
If you still fave the issue you can report this to the Microsoft team. You can raise feedback to the Microsoft team.
