This error comes only when Toolset Views is active. If I deactivate it, everything works ok. I have tried to deactivate all the other plugins, but no help. With the error, there are buttons "Attempt recovery" (doesn't do anything) and "Copy error", which gives as pasted this:

Hello and thank you for contacting Toolset support.

I wonder if this issue is the one that was discovered for WPML and WP5.8.1 https://wpml.org/errata/wp-5-8-widget-translations-not-working-for-local-code-languages-with-a-hyphen/

Please try the workaround on that article, and if it does not fix the issue. We'll need to get a closer look and see how that is produced. We'll need access to your website and the steps to follow to see it. Your next reply will be private to let you share credentials safely. ** Make a database backup before sharing credentials. **

I'm getting the same error and the article linked about only works if you have "sitepress-multilingual-cms" installed. Which I don't. Should I create another ticket?
