Although I was able to fix my issues this time, for future reference when problems with new versions occur:
Even without a snapshot you can install the previous version of homeassistant. There are several ways to do this.
Here is how I do it:
Open homeassistant in google chrome (may work with other browsers?).
Right click on the web-page.
Choose “Inspect” from the menu
Select the “Console” tab in the window.
Paste the following in the console window:
javascript:document.querySelector('home-assistant').hass.callApi('post', 'hassio/homeassistant/update', {version: '0.85.2'})
You can change the version to whichever you need.
This will roll back or update homeassistant to whichever version you specify.
