Just got it....

Had to do like in this workaround: https://github.com/linux-surface/linux-surface/issues/654#issuecomment-983586694

After changing this in /etc/default/grub it works.

Same here.

The Surface 7 touchscreen stopped working after updating from kernel version 6.6.6 to 6.7.9 and from iptsd 1.4 to 2. The Surface 7+ (note the '+') with the same software is fine.

As linked above, the solution is to disable intel_iommu.

How to:

Edit /etc/default/grub.
Add intel_iommu=off to the end of the GRUB_CMDLINE_LINUX_DEFAULT variable, so it looks like something like this: GRUB_CMDLINE_LINUX_DEFAULT="quiet splash intel_iommu=off".
Save and quit the editor.
Run sudo update-grub.
Profit.
