Sorry to hear that.

The OutOfBounds message and the stack trace reminds of a bug that we
have fixed in a newer version of BaseX (even 8.6? not sure anymore).
As you already guessed, the only thing I can recommend for now is to
update to the latest version. If a database should get corrupt in a
recent version, it is always easier for us to track down what might
have gone wrong.

Best,
Christian
