Hi Seb,
I am an IT specialist and this is the first time I wasn't able to fix an issue. In my opinion the only way to fix this is replace the laptop. But there is also good news. If you contact MS Business Support (if your company bought the laptop you can contact business support) there is a service that will first send you a new laptop and you will have 2 weeks to install everything on it before you have send your current laptop back to Microsoft.
This service is standard for all Surface Laptops that are bought by a Business.
Thank you. I bought this laptop as a non-business user though. I emailed their customer service and will see. Thought there might be a chance this could be fixed through an update but perhaps not.
