When API error 401 is present, the block editor is broken due to fatal error regarding WP_Error

[LoganStrike]

Description

When the following error appears on the IMPress Initial Settings page in WP Admin, the WP block editor is also broken, preventing all pages from being edited:

Error 401: Access key is invalid or has been revoked, please ensure there are no spaces in your key.
If the problem persists, please reset your API key in the IDX Broker Dashboard, or contact [email protected]

I'm getting a similar error as reported above, although there is no API error in this case and the stack trace is not identical. It looks like it may be related so I'll post it here. Let me know if this needs to be a separate issue instead.
