Hi
Attached is a piece of code to produce an 11 by 11 matrix in round
brackets. It throws an error on compilation of
"Extra alignment tab has been changed to \cr.
& & & & & & & & & &

You have given more \span or & marks than there were
in the preamble to the \halign or \valign now in progress.
So I'll assume that you meant to type \cr instead."
However a 10 by 10 matrix works fine.
for some historical reason the number of columns is limited to 10!
Write into the preamble
\setcounter{MaxMatrixCols}{11}

Thanks - I had hoped that later versions of lyx might have done this
insertion automatically. It does other such automatic preamble additions.
Is this a problem with my set up, which is Ubuntu 22.04.5 LTS, LyX
Version 2.3.6?
