**Your software**
My Mautic version is: 4
My PHP version is: 7.4.3
My Database type and version is: 8.0.28-0ubuntu0.20.04.3
**Your problem**
My problem is: I’ve tried to change from the default Dashboard reports to another pre-existing template. Now my Dashboard shows the “We’ve found a bug” error message and I can’t turn it back.
Any ideas?

Does anything shows in the log? Any error?

Does this mean anything?

You mentioned dashboard above but the error comes from email bundle. I am not so sure I can visualize a problem as well as I thought at first. Could you please provide some screenshots from the GUI (are we talking about widgets or reports - or maybe even something else).
At first glance nothing obvious comes to mind, so it might be a bug.
Thanks.

Not a lot to say on that one if honest. It’s literally just the 500 Internal Server Error message.
