I know this sounds weird but my 2018 11 inch pro started acting up about a month ago. It was having all of the symptoms that others have been complaining about where the touch screen becomes unresponsive for a few seconds. Sometimes it just freezes for a while. A reboot would make things better but the issue always comes back. It was driving me crazy so I tried uninstalling apps, doing a full system factory reset, etc. Nothing worked until I tried using the original charger. I had been using a 27 watt charger from monoprice. I rebooted and started using my apple charger and the issues with the touch screen have not happened again for 2 days now. Could a charger cause some weirdness with the touchscreen?
