I've installed the latest Magento Version (2.3) and everythign went well. The installation was completed and i was able to view and frontend aswell the backend.
For some reason i get the following error on the backend and the loading spinner keeps spinning forever. Sometimes, after a refresh, the spinner goes away but no menu items are clickable. In the Chrome DevTools i get various of errors displayed, especially with knockout.js or knockout related files.
