Uncatchable exception

Since yesterday, every query I run results in a yellow information bar at the top of the query window that says

Query ended because an uncatchable exception was thrown.

There is a delay, then the query runs anyhow. It even happens with the language set to C# Statement(s) and no connection selected for this:

int i = 10;
i.Dump();

I do have references to a number of custom assemblies set as query default, but I removed all such references for this query and still receive the error.

What's happening and how can I fix it?

Thanks!

    Unfortunately, this issue returned after a while. It's extremely frustrating. Again, even a query like "42".Dump(); causes this exception text to be shown before producing the expected output. The frustrating part is that there's a 2-5 second delay before my actual query starts to execute when this happens.
  • If there really is an uncatchable exception thrown (StackOverflowException or AccessViolationException) there should be an entry in the event-log that tells you which one it is.

    If this happens often I would try to catch the bug with DebugDiag, however I would suspect a problem with your system in this case.
