Hi, Bentwerx
Thanks for posting, and welcome to the Roku Community.
We appreciate you for sharing this information with us, and we're sorry to hear about the trouble.
Let's try to troubleshoot this by performing a complete restart of your Roku streaming device. A reset button is located at the back of your Roku streaming device Is a button or a pinhole that requires a clip to be pressed and held for 20 seconds while the Roku device is turned on. After this, the device will boot and see if it's able to restart for another set-up process.
Keep us posted on how it works.
All the best,
Kash
