**Your software**  
My Mautic version is: 5.0.4  
My PHP version is: 8.1.28  
My Database type and version is: pdo\_mysql 5.7.44-48-log

**Your problem**  
My problem is: I am unable to Edit existing campaigns or create new campaigns from Scratch.

Creating even the most basic campaign, with one segment, followed by an email send will fail to save and the application errors with a 500 Server error:

The first step is to update to the latest version available, in this case, 5.2.4, to see if the problem persists.

The first versions of Mautic 5 had many bugs.
