ESPHome gives blank screen in Home Assitant

I can’t change the ESPHome config anymore. If I click on ESPHome in the navigation bar on the left there is only a blank screen. The ESP32 is still alive. I can still can use it. I reinstalled it. but no luck. When I reinstall it finds the ESP on the network.

What do the logs say?

Found it. I discovered that the problem not existed in the App’s and also not in Firefox. After clearing the cache in Chrome the problem was solved.
