You can probably see more information from log files. Without a full stacktrace it's almost impossible to understand what is wrong
I know it's been a few months, but we are also seeing this error. The log files are not showing anything useful. We do see this message in the dev console:
_317 {message: 'Unable to load /EPiServer/cms/Stores/contentdata/159007_467443 status: 409', response: {…}, status: 409, responseText: '[{"severity":3,"errorMessage":"Object reference not set to an instance of an object."}]', xhr: XMLHttpRequest, …}

Error
Our customer has encountered this issue as well but we couldn't reproduce it since there's no way to trigger the error. We suggested that the customer has their devtools open during the edit process and send the logs to us if they encounter a problem but the error has not happened since then. They did tell us, however, that the error seems to happen more often when working with blocks in a content area. As of today, we still have an open ticket with the support but we have no error log to send to them.

"Could not save property, Please reload the page"
Has anyone experienced this and eventually have some tips for debugging and solving it?
It's CMS v12.22.1
Thanks in advance and best regards.
