How to run Xcode 10.2 Simulator

Question

Overnight my Xcode has update to 10.2 and ever since I can't run the simulator anymore. Affected seems every Simulator regardless of Model or iOS Version.

Xcode is building and showing "Running on iPhone X", but I can't see a simulator.

I have the Simulator Icon in the Dock, but clicking on it leads to Xcode.

"Show all Windows" on the Icon just brings me "No Available Windows" on my Screens.

I have restarted Xcode and iMac. Help is very appreciated.
